High strain rate properties of SiC/AZ31B nanocomposites under low temperature

In this paper, the deformation behaviours of AZ31B magnesium alloy and AZ31B reinforced composites (AZ31B-SiC0.5% and AZ31B-SiC1%) under different strain rates at low temperature were studied. Compressive Split Hopkinson Pressure Bar was used to conduct the experiment and the three materials were su...
