ME 322 - Engineering Materials

3 lecture hours 2 lab hours 4 credits
Course Description
The course covers the relationship between structure, properties, and processing in engineering material. The primary emphasis is on metals. Basic concepts of solidification and heat treatment are presented. Alloy phase diagrams and lever rule calculations are shown as a means to understanding both solidification and heat treatment. The relationship between processing/heat treatment and the underlying related strengthening mechanisms are presented. Material selection in terms of mechanical strength service stability, cost, and environmental impact are discussed. (prereq: ME 321 )
