MSE 557

Deformation Processing

Sem. 1. Class 3, cr. 3. (offered in alternate years). Prerequisite: senior or graduate standing in engineering or science.

MSE 557 is an elective course.

Weekly Schedule: Three 50-minute lectures.

Presents the consistent phenomena demonstrated in deformation processing of metals, ceramics, and polymers. The development of laminated or "sandwiched" structures consisting of polymers and metals, mechanically-assisted high temperature powder densification, and predictive models for crystallographic texture effects during hot working are but a few of the many examples wherein deformation processing can straddle the boundary between the traditionally distinct topics of metal forming and fluid flow. Topics include: crystal plasticity, viscous flow (Newtonian and non-Newtonian), microstructural origins of deformation behavior, isotropic and anisotropic yield criteria, upper bound analysis, an introduction to slip line fields, rolling, drawing, extrusion, tape casting, superplastic forming, roll bonding, texture development, and assessment. Offered in alternate years.

Relation of Course to Program Outcomes
1. an ability to apply knowledge of mathematics, science, and engineering to problems in materials engineering.
5. an ability to identify, formulate, and solve engineering problems, particularly in the context of materials selection and design.
7. an ability to exhibit effective oral and written communication skills.

•  To understand classical perspectives on metal forming.
•   To recognize differences between metal forming approaches and rheological approaches to shaping technologies.
•   To understand mechanisms leading to preferred orientation and the effects of preferred orientation on properties.
