Observation of shear bands in the Vitreloy metallic glass subjected to HPT processing

The parameters of shear band evolution with deformation were examined in the Vit105 bulk metallic glass. For this purpose, two halves of disks of the bulk metallic glass were joined together and processed by high-pressure torsion for various strains: from compression without rotation, to rotation for 5 revolutions. The discrepancy between the experimentally observed and predicted shear strains was detected. The actual strain is significantly...
