Dr.Placid Rodriguez Memorial Lecture
(PRML)- 2015
Dr. Placid Rodriguez (1940-2008), a renowned metallurgist and eminent scientist and technologist, had significantly contributed to the advancement of science and technology in our country by (i) establishing the vibrant field
of nuclear metallurgy, (ii) leading the country to fast breeder technology, (iii) developing human resources for DRDO,
and (iv) teaching and nurturing young students and researchers at IIT, Madras and NITs. Dr.Placid Rodriguez played
a very decisive role in shaping the activities of The Indian Institute of Metals, at the national level.
The Indian Institute of Metals has instituted ―Dr.Placid Rodriguez Memorial Lecture‖ in memory of Dr.Placid
Rodriguez, to perpetuate his significant contributions to science and technology by organizing a memorial lecture
every year. This idea has been instantly welcomed and sponsored by DRDO and BRNS. Kalpakkam and Chennai
chapters of IIM have organized the memorial lecture every year, as a mark of respect to Dr.Placid Rodriguez.
Dr.Placid Rodriguez Memorial Lecture Series was first inaugurated by Dr.Baldev Raj, President (Research), PSG
Institutions, Coimbatore on November 26, 2009 at Indira Gandhi Centre for Atomic Research, Kalpakkam. Since
then, eminent metallurgists like Prof. Atul Chokshi, IISc., Bangalore, Professor Seeram Ramakrishna, National University of Singapore, Dr. S.Srikanth, Director, National Metallurgical Lab., Prof. B.S.Murty, IIT, Madras, Prof. Indranil
Manna, IIT Kanpur, and Dr. Amol A. Gokhale DMRL, Hyderabad, have delivered Dr. Placid Rodriguez Memorial Lecture.
The Seventh Placid Rodriguez Memorial Lecture was organised on October 5, 2015 at Sarabhai Auditorium, IGCAR Kalpakkam. Dr. U. Kamachi Mudali, Member, PRML Committee, Outstanding Scientist and Associate
Director, Corrosion Science & Technology Group, and Materials, Process & Equipment Development Group, IGCAR,
warmly welcomed the gathering Prof. M. Kamaraj, Member, PRML Committee, Head, Dept. of Metallurgical and Materials Engineering, IIT Madras, briefly dwelt upon the genesis of Dr. Placid Rodriguez Memorial lecture and the details of the series of lectures conducted since 2009. Dr. S.A.V. Satya Murty, Distinguished Scientist & Director, IGCAR, the chief guest of the function, recalled his association and valuable contributions of Dr. Placid Rodriguez for
IGCAR and expressed his happiness to be part of the event.
Dr. G.K. Dey, Distinguished Scientist & Associate Director, Materials group, BARC, Mumbai was invited to
deliver ―Placid Rodriguez Memorial Lecture-2015‖ on ―Development of Alloys for Application in the Nuclear Energy
Sector: Some New Perspectives‖. Dr. S. Venugopal, Outstanding Scientist & Director, Metallurgy and Materials
Group, IGCAR introduced the PRML 2015 speaker Dr. G.K. Dey, currently the Associate Director of Materials Group,
BARC, Mumbai. Dr. Dey is well known for his excellent contributions in Phase Transformation in Zirconium and
Nickel Base Alloys, Amorphous Alloys, Rapidly Solidified Crystalline and Quasicrystalline Alloys, Electron Microscopy
and defect Characterization and High Resolution Electron Microscopy. Dr. G.K. Dey has won several awards and to
name a few prestigious ones: MRSI Medal given by Materials Research Society of India (2001), Metallurgist of the
year award by Ministry of Steel (2003), the Vasvik Award (2006), the G D Birla Gold Medal of Indian Institute of Metals (2011), and the Distinguished Alumnus Award of IIT BHU. He is also a Fellow of many prestigious professional
organizations.
Dr. G.K. Dey explained that uninterrupted operation of nuclear reactors is highly dependent on the performance of the structural materials which have to perform under severe service environments. In this respect any alloy
which could be considered for structural application in a nuclear reactor has to have high corrosion resistance, adequate mechanical strength at elevated temperatures, and should withstand deleterious irradiation effects. Dr. Dey
emphasized the importance of optimization of the desired properties for the chosen alloy which requires control of the
microstructure that depends on manufacturing processes. He explained three categories of alloy development strategies as (i) replacement of commercially imported alloys with indigenous alloys having similar or better properties, (ii)
development of new alloys using empirical approach, and (iii) development of new alloys using ab-initio approach. Dr.
Dey’s presentation elucidated many examples in the case of recent indigenous development of Zr based alloys,
VOLUME 6, ISSUE 1, 2016
Page 08
Nb based alloys, steels and nickel based alloys. He also highlighted structure -property correlations,
effects of neutron irradiation and simulated ion irradiation in these alloys. Dr.Dey emphasized that considerable
efforts are needed in attaining the capability of alloy development by ab-inito approach. The lecture was very
well received by the 300-350 scientists and young research scholars who had participated in the event.
Dr. S.A.V. Satya Murthy presented the PRML memento, to Dr. G.K. Dey and he also released the PRML

Phase Stability and Phase Transformation Kinetics Studies in
Uranium rich U-Zr Alloys using Calorimetry and Microscopy
Techniques
Arun Kumar Rai, Microscopy and Thermo Physical Property Division, IGCAR, Kalpakkam
With the revival of interest in nuclear power program, it has become necessary to develop the required
knowledge base on advanced structural and fuel materials for enabling the knowledge driven pursuit to
component design, fabrication and performance testing of advanced generation IV reactor concepts [16]. In India, the emerging interest on metal fuelled and liquid metal cooled fast reactors has ushered in a
spurt of research activities on diverse fronts related to materials processing and spent fuel reprocessing
technologies [6]. As an integral part of this technology development initiative, it has been decided to investigate the physical metallurgy of some of the relevant uranium based metallic systems which are
identified as potential fuel candidates. It is well known that the optimal choice of fuel depends on a host
of factors such as, high temperature in-pile stability, irradiation induced swelling and elemental redistribution characteristics, thermal expansion and thermal conductivity behavior, compatibility with clad and
coolant etc. [1-14]. Among many probable metal based nuclear fuels, the U-20 wt.%Pu-10wt.%Zr ternary combination is touted as one of the potential materials, owing to its certain intrinsic merits that includes, the high fissile atom density, short doubling time and enhanced breeding gain, good compatibility with steel clad and liquid metal coolant [1-6]. However, the fuel present inside the core of the reactor
is bound to experience numerous thermal transients under temperature gradient and hence phase
change cycles, therefore a study of phase stability and phase transformation are of utmost importance in
accessing fuel performance [1-6]. In this regard, reliable experimental data on basic thermodynamic and
kinetic quantities of different phases as a function of temperature and composition are required on all
three binaries that constitute the ternary U-Pu-Zr metal fuel, namely U-Zr, U-Pu and Pu-Zr. Among these
binaries, a study on high temperature phase stability and phase transformation kinetics in U-Zr alloys as
a function of thermal history and Zr content are important in understanding of actual behavior of fuel during service condition [7-14]. The phase transformation in U-Zr based alloys have attracted considerable
attention for a long period because the transformation sequence involve many stable and metastable
phases that form during cooling from high temperature phase [8-13]. In U-Zr system, the broad phase
diagram features have been established fairly [14], however finer aspects related to various phase transformation thermo-kinetics data base still remain to be established beyond doubt. In this context, a systematic characterization of phase stability and phase transformation kinetics in U and U-Zr with Zr content varying between 2 to 10 wt. % have been carried out in the present study using differential scanning
calorimetry (DSC) and microscopic techniques.
Before proceeding further a brief account of phase equilibira of U-Zr system is given as follow.
As per the recently accessed phase diagram of U-Zr system, the U-Zr binary is characterized by the
presence of five phases. They are: α-U (orthorhombic), β-U (tetragonal), γ - (U, Zr) (bcc), α-Zr (hcp) and
δ-UZr2 (AlB2-w type structure) is an intermetallic compound. Further, for alloys having a Zr content between 5 to 22 wt.% Zr, the high temperature γ phase exhibits a phase separation into two bcc phases,
namely γ1 (rich in uranium) and γ2 (rich in Zr), below about 1023 K(750oC). In the present study using
DSC the effect of heating/cooling rates and Zr content on the phase transformation sequence in U-0, 2,
5&10 wt.% Zr alloys has been monitored. Using DSC, the complete phase transformation sequence up
to melting have been measured at slowest heating rate of 3 K min -1 for U, U-2, 5 & 10 wt.% Zr alloys. A
typical DSC thermo-gram for U-2wt%. Zr is given in Fig. 1. In the case of uranium the following solid
state phase transformation sequence is observed: α→β→γ during heating cycle. On the other hand, in
the case of U-2wt.% Zr alloy, the transformation sequence is: α(α’-distorted orthorhombic)+ δ-UZr2 →
α+γ2 → β+γ2 → β+γ1 → γ. For alloys of 5 and 10 wt.% Zr content, the additional presence of a miscibility
gap (γ1 U rich bcc + γ2 Zr rich bcc) in the high temperature γ(bcc) phase region resulted in the following
transformation sequence: α(α’)+δ UZr2 → α +γ2 → β+ γ2 → γ1+γ2 →γ. Further, it has been demonstrated

Fig.1. DSC thermogram obtained for U- 2wt.% Zr alloy at 10 K min-1. An expanded
view of the first composite endothermic thermal arrest arising due to the cooccurrence of martensitic relaxation and δ-UZr2 dissolution is also shown.
that in the case of U-2, 5 & 10 wt.% Zr alloys, depending on the nature of starting microstructure,
namely whether it is α’-martensite,αeq+δ-UZr2,or a mix of
α’+αeq+δ-UZr2 phases, the relative extents of two possible co-occurring transformation modes (α’martensite relaxation and dissolution of δ-UZr2) differs. It has been noticed that the co-occurrence of
these two events gives rise to a composite thermal arrest in the normal on-heating DSC profile and corresponding result is shown in Fig. 2. In addition, the decomposition of high temperature γ(bcc) phase as a
function of cooling rate and Zr-content has been studied using DSC and metallography. It has been observed that it is not possible to obtain 100% of αeq phase along with equilibrium amount of δ-UZr2, if the
cooling rate is more than 0.1 K min-1. The cooling rate from high temperature g(bcc) is found have a
strong influence on microstructure evolution as well. Further, the continuous heating and cooling transformation diagrams have also been obtained for U-2, 5 & 10 wt.% Zr alloys in the present study. A typical
CCT diagram for U-2wt.%Zr alloy is shown in Fig. 3. From CCT diagram it has been observed that critical
cooling rate for γ → α’ direct displacive transformation is found to decrease with increasing Zr content For
U- 2, 5, and 1 0 wt.% Zr allo ys , it is f ound to be of the order of , 60, 20, 10 K m in - 1 .
Additionally, the kinetic aspects of α→β and β→γ transformations that occurs on heating have
been modelled using Kolmogorov-Johnson-Mehl-Avrami (KJMA) formalism. The experimental fraction of
transformation data for α→β phase change in U-2wt.% Zr alloy have been fitted using KJMA model by
means of a standard non-linear optimization routine. The fit along with the experimental X b(T) data are
shown in Fig. 4. The figure shows that both experimental data and the KJMA model fit are in good agreement. It has been observed that in the case of uranium, the transformation kinetics is interface controlled,
however, in the case of U-2, 5 & 10 wt.% Zr alloys, the kinetics is controlled by the diffusion of Zr in α’orthorhombic phase. It has been observed that with increasing Zr content of alloy, the effective activation
energy Qeff, is increasing. This is in line with the observation that solid state diffusion becomes progressively more sluggish with increasing Zr-content, which is one of the reasons, as to why γ→α’-displacive
transformation is favored rather easily in high Zr containing U-Zr alloys.

In summary it may be stated that in the present study the complete sequence of various transformations that occur during heating and cooling cycles in U-2, 5 & 10 wt. Zr alloys has been established beyond
doubt. The presence of UZr2 phase even in dilute U-Zr alloys has been unambiguously confirmed. Further, the
co-occurrence of martensitic relaxation and δ-UZr2 dissolution in U-2, 5 & 10 wt. Zr alloys has been clearly
observed if the initial microstructure has martensitic α’ phase using a combination of DSC and metallography.

shown as continuous line, passing through experimental data points,
shown as filled circles.
In addition, the effect of cooling rate and Zr content on the decomposition of high temperature γ phase has
been studied. It has been observed that depending on Zr content and cooling rate, the decomposition of γ
phase may adopt either diffusional or martesitic mode of transformation.

Editorial
It is an honor for us to bring out the current IIM-KC
newsletter. The past year was filled with lot of events, in
which the chapter actively participated. It played a pivotal role in organizing the NMD-ATM 2015. The chapter
jointly conducted the 7th International Conference on
Creep, Fatigue and Creep-Fatigue interaction. The second Young Scientist/Metallurgist Colloquium was held
this year. This program served as a right platform for
young researchers to exchange technical/scientific ideas
and to enhance their presentation skills. The 23rd Prof.
Brahm Prakash Memorial Materials Quiz was held in a
grand manner. This year’s Placid Rodriguez Memorial
Lecture was delivered by Dr. G. K. Dey. A number of
technical lectures were delivered this year by eminent
people across various disciplines pertaining to metallurgical and materials engineering. The excerpts of all
these events and lectures have been presented in this
newsletter. This has been another successful year for
many for our members, the detailed list of their awards
and honors is also reported.
