Science of Engineering Materials

Instructor: Dr. Alexander S. Mukasyan

Course Summary

The course “Science of Engineering Materials” is an original course, which provides students a comprehensive knowledge on the relationship between materials structures, processing conditions and their properties. It involves the analysis of wide range of materials, such as metals and alloys, ceramics and polymers, composites and bio-materials. Pre-requisite are: undergraduate courses in Chemistry, Physics and Materials Science. Qualification work includes exam and term paper on the different aspect of advanced materials.

Science of Engineering Materials is a broad, multidisciplinary field devoted to understanding and manipulating the mechanical, electrical, optical and magnetic properties of materials. It is closely related to chemical and mechanical, electrical and computing, bio- and civil engineering. It studies fundamental characteristics of a variety of materials including metals, ceramics, polymers, and electronic materials.

This course considers: (a) how the physical properties of metals, ceramics polymers and composites are correlated with their internal structures (on atomic, molecular, crystalline, micro- and macro- scales) and operational conditions (mechanical, thermal, chemical, electrical and magnetic); (b) how materials processing, e.g. mechanical working and heat treatment, affects their properties, as well as environmental behavior. The latest achievements in Materials Science and Engineering are also discussed. The main course goal is to develop an awareness of materials and their properties.
