Engineering Science

201. Engineering Materials  Atomic structure; crystallographic concepts; relationship of structure to properties of metals, ceramics and organic materials. Equilibrium and non-equilibrium relationships of multi phase materials. Methods for changing properties of materials. Three lectures, three-hour laboratory every second week.  Fall and Spring (Cr.3)

Prerequisite: CHEM 101

Course objectives:

The student will be able to:

  • Study the measurement and significance of mechanical, electrical and thermal properties of materials  (hardness, strength, ductility, various types of elastic moduli, electrical and thermal conductivity).

  • Study and analyze crystal systems, with emphasis on crystal structure, x-ray diffraction and crystal imperfections.

  • Study methods of controlling properties through alloying, plastic deformation and recrystallization.

  • Examine techniques for constructing and analyzing phase diagrams, including material balances (inverse lever law).

  • Examine the iron-carbon (steel) system, covering such topics as: the Fe-C phase diagram, equilibrium and non-equilibrium phases, processing methods for property control, hardenability, and cast irons.

  • Study electronic structures and processes, with emphasis on the nature and properties of semiconductors.
