MISSION STATEMENT
The Department’s mission is to carry out educational programs
to graduate high quality, nationally and internationally recognized
engineers with strong backgrounds in materials related scientific
and engineering problem-solving methods.
UNDERGRADUATE PROGRAM
The Department of Metallurgical and Materials Engineering is
concerned with the generation and application of knowledge on
engineering materials. It comprises such aspects as the extraction and
refining processes, synthesis and processing of materials, factors
affecting the internal structure of solids, methods of altering the
structure and properties of materials and factors affecting the materials
behavior in service.
The undergraduate curriculum comprises a core program that
emphasizes principles basic to all these classes of materials. It builds
upon courses on physics, chemistry and certain aspects of solid
mechanics with a series of courses on internal structure of solids
covering both chemical and physical aspects and structure-property
relations. From the fifth semester on, the core curriculum addresses to
career opportunities in metallurgical and materials engineering. These
include the metal industries, ceramic industries and other small scale
industries that normally deal with a variety of materials. In addition to
its solid core program department offers various technical elective
courses on various aspects such as nanomaterials, energy, biomaterials,
extractive metallurgy, electrical,
magnetic and optical properties
of materials. Students take
capstone design project in their
senior year, by pursuing a real
world engineering application.
GRADUATE PROGRAM
Graduate programs in METE are designed to present the students with
systematic development of the fundamental scientific and engineering
principles underlying materials phenomena and process operations.
The department offers 3 types of graduate programs
• M.S.
• Ph.D.
• Integrated Ph.D. Program
Course Requirements: M.S. students are required to take
minimum of 7 courses apart from a Master's thesis. Program
involves 3 compulsory courses, seminar and the remaining
courses are restricted electives which are taken by the student
in close cooperation with their advisors.
For the Ph.D. Degree, an additional 7 courses and a Ph.D. thesis
should be successfully completed.
In integrated Ph.D program, the students are required to take a
minimum of 14 courses in addition to Ph.D. thesis.
