The Effect of Strain Rate on the Fractrure Modes of Mg Alloys
Advanced Materials Research Vols. 26-28 (2007) pp 1221-1226，-0001，（）：
Bending and impact tests were conducted on magnesium alloys AZ31 and AZ80 in different microstructure conditions. It is found that the strength parameters are increased quite a lot, and the ductility parameters (bending flection) decreasedwith increase in strain rate. The damaged surface analysis in SEM revealed that, the micro crack nucleation modes, icro crack coalescence and final crack path are varied with the stress state on the specimen, and the crack nucleation modes are varied with the initial strain rate. The effect of strain rate on fracture modes is discussed.
