ABHYAS :warning:
FCC
High dependency on dislocation density
More dislocations , more resistance you get.
Lots of slip systems
DISLOCATION via Edge dislocation
BCC
Low dependency on dislocation density
Brittle - Ductile transition
Less slip systems
DISLOCATION via Screw dislocation
Stage 3 Twinning Mechanism
at low temperatures, Sensitivity of flow stress decreases against strain rate and T.
Stage1 Athermal Mechanism
Flow stress independent of both T and Strain rate
Stage 4 Dampening mechanisms
Very high strain rates > 1000
Stage 2 Thermally activated mechanism
