Abstract

Evolution of internal parameters of metallic glasses subjected to high pressure torsion was simulated using a free volume based thermo-mechanical model. Steady state has been predicted in the whole, plastically sheared volume for large strains irrespectively from the applied revolution rate. Based on the simplification of the model equations in steady state, simple methods were obtained to determine the in situ temperature increase and stress distribution from external torque measurements.
