ME 330

Structures of polymers, metals, and ceramics as the basis for their mechanical behavior. Manipulation of structure through such processes as heat treatment and solidification. Mechanisms of material failure in service (yielding, fracture, fatigue, creep, corrosion, and wear) and simple design techniques to avoid these failures. Strategies for materials selection in design. Course Information: Credit is not given for both ME 330 and either CEE 300 or MSE 280. Prerequisite: CHEM 102 and TAM 251. Class Schedule Information: Students must register for one lab and one lecture section.

Structures of polymers, metals, and ceramics as the basis for their mechanical behavior. Manipulation of structure through processes such as heat treatment and solidification. Mechanisms of material failure in service (yielding, fracture, fatigue, creep, corrosion, wear) and simple design techniques to avoid these failures. Strategies for material selection in design. Prerequisite: TAM 251, CHEM 102 or equivalent. Students may not receive credit for both this course and MSE 280, TAM 324, or CEE 300. (The latter two courses are cross-listed.) 4 undergraduate hours.

1. Mechanics of materials: properties of materials (mechanical, thermal, optical, electrical); bonding, properties and classification of materials, crystallography; dislocations and vacancies; work hardening and plasticity; forming processes (wire drawing, rolling, forging, annealing, recrystallization, grain growth)

2. Polyphase materials: phase diagrams, strengthening mechanisms, nucleation, diffusion and growth, heat treatment processes (solution, quenching and heat transfer, aging, IT and CCT diagrams, commercial processes)

3. Solidification: cast micro- and macrostructures, solidification processing (casting, solidification time, stresses of solidification), welding and joining processes
