Abstract
Room-temperature rolling experiments were performed on Pd40Ni40P20 bulk metallic glass at two different strain rates. It is found that at each strain rate the shear band density increases with increasing strain for the deformed samples. However, for samples endured the same deformation strain, more amounts of shear bands (i.e., a higher shear band density) was introduced into the sample deformed at the higher strain rate. In addition, the higher strain rate also leads to the generation of more amount of free volume for samples endured a same deformation strain. The hardness change behavior investigation result suggests that the introduction of multiple intersected shear bands leads to hardening of Pd40Ni40P20 bulk metallic glass.
