Scope and Objectives
At the heart of materials
science is an understanding of the microstructure of solids.
"Microstructure" is used broadly in reference to solids viewed
at the subatomic (electronic) and atomic levels, and the nature of the
defects at these levels. The microstructures of solids at various
levels, especially the defects, profoundly influence the mechanical,
electronic, chemical, and biological properties of solids. The
phenomenological and mechanistic relationships between the
microstructure and the macroscopic properties of solids are, in essence,
what the materials science is all about. This is best represented by the
"materials science triangle":
synthesis-microstructure-properties.
Materials engineering, on the
other hand, is concerned with the design, fabrication, and testing of
engineering materials. Such materials must fulfill simultaneously the
dimensional properties, quality control, and economic requirements.
Several manufacturing steps may be involved: (1) primary fabrication,
such as solidification or vapor deposition of homogeneous or composite
materials; (2) secondary fabrication, including shaping and
microstructural control by operations such as mechanical working,
machining, sintering, joining and heat treatment and (3) testing, which
measures the degree of reliability of a processed part, destructively or
non-destructively.
Because the science of
materials branches into other fields of study, the department offers
joint fields of study in collaboration with other departments. A degree
specializing in electronic materials is offered which provides a
broad-based background in materials science, with the opportunity to
specialize in semiconducting materials used in electronic and
optoelectronic devices. The program incorporates several courses in
electrical engineering in addition to those in the materials science
curriculum.
A joint major field,
chemistry/materials science, is offered to students enrolled in the
Department of Chemistry and Biochemistry (College of Letters and
Science). Several courses in the undergraduate curriculum also play an
important role in the manufacturing engineering program.
The graduate program allows
for specialization in one of the following fields: ceramics and ceramic
processing, electronic and optical materials, and structural materials.
