Basics of plastic deformation – Mohr’s circle – yield theories – plastic stress – strain relationship – plastic work – constitute relationships – mechanical working – work hardening.
Analysis – slab analysis – upper and lower bound theorem – exact solutions – slip line field theory and its solution – numerical methods and FEM.
Severe plastic deformation by ECAP – types – microstructural variation with different processing routes – multichannel ECAP – strain distribution and texturing.
SPD by cryo rolling – process – types – microstructural variation with stress – strain distribution.
SPD by mechanical alloying – introduction – types of equipment – compaction – sintering – HIP, SIS – mechanism of sintering.
