Interfacial kinetic barriers and elastic stress on diffusion are presented. Modern surface analytical techniques, such as Auger, ESCA, and SIMS, are considered. Fundamental aspects of crystal plasticity are then considered, along with the methods for strengthening crystals at low temperatures. Deformation at elevated temperatures and deformation maps are also covered. Emphasizes the relationships between microscopic mechanisms and macroscopic behavior of materials.
Continuum fracture mechanics principles are presented.
Cleavage, ductile fracture, fatigue, and environmental cracking are included, with emphasis on micromechanical modeling. Cross-listed as AM 732 . The nature and major effects of crystal defects on the properties of materials are studied, with an emphasis on metals. The elasticity theory of dislocations is treated in depth. Permission of instructor Emphasis on the nature and types of polymers and on methods for studying them.
