Abstract

Bulk metallic glasses feature pleasing properties which are promising for applications, because of which they have reached increasing attention. Metallic glasses exhibit mechanical properties such as high strength and hardness, however, this advantage is impeded by the fact that their plasticity appears to be extremely meager. The plastic deformation is localized in thin regions, called shear bands, with widths from 10nm to 50 nm, whose extension lead to catastrophic failure. In the section of shear bands, there is an amount of research to be performed concerning the initiation, propagation, kinetics and general comprehension of shear banding. In the present study, the effort is made to understand the mechanism of shear banding in a Pd40Ni40P20 bulk metallic glasses more precisely. The investigation focuses on the kinetic and structural properties of this special bulk metallic glass by the use of various experimental techniques.
