Unformatted text preview: • How do dislocations participate in plastic damage? • What type of stress is needed? (tensile or shear) • How do dislocations interact with one another? • How does crystallinity play a role in plastic yielding? • Slip systems • Resolved shear stress and critical resolved shear stress • Strengthening mechanisms -Grain boundaries (smaller grains stronger, less ductile) -Alloying or solid solution strengthening (increased alloying results in stronger, less ductile) -Work or strain hardening (more % CW, increased strength, less ductility, reversible ) -Precipitation hardening • Recrystallization and recovery (What is recrystallization temperature) Chapter 8: Failure • Ductile, Semi-ductile, and brittle fracture...
