Notizen:
Bending and impact tests were conducted on magnesium alloys AZ31 and AZ80 indifferent microstructure conditions. It is found that the strength parameters are increased quite a lot,and the ductility parameters (bending flection) decreased with increase in strain rate. The damagedsurface analysis in SEM revealed that, the micro crack nucleation modes, micro crack coalescenceand final crack path are varied with the stress state on the specimen, and the crack nucleation modesare varied with the initial strain rate. The effect of strain rate on fracture modes is discussed
