Abstract

In order to estimate the temperature rise generated by the extreme shear during high pressure torsion deformation, a simple model based on the one-dimension heat-conduction equation was proposed. Calculations have shown that the average temperature in the sample can slightly exceed the glass transition temperature above a critical strain. The experimentally obtained shear dependent microstructure and morphology of an amorphous Cu60Zr30Ti10 alloy are consistent with the calculated temperature profiles.
