AbstractRepetition and advancement of dislocation theory. Mechanical properties of metals: hardening mechanisms, high temperature plasticity, alloying effects. Case studies in alloying to illustrate the mechanisms.
ObjectiveRepetition and advancement of dislocation theory. Mechanical properties of metals: hardening mechanisms, high temperature plasticity, alloying effects. Case studies in alloying to illustrate the mechanisms.
ContentDislocation theory:
Properties of dislocations, motion and kinetics of dislocations, dislocation-dislocation and dislocation-boundary interactions, consequences of partial dislocations, sessile dislocations
Hardening theory:
a. solid solution hardening: case studies in copper-nickel and iron-carbon alloys
b. particle hardening: case studies on aluminium-copper alloys
High temperature plasticity:
thermally activated glide
power-law creep
diffusional creep: Coble, Nabarro-Herring
deformation mechanism maps
Case studies in turbine blades
superplastizity
alloying effects
