Abstract

A model is described which makes it possible to calculate the value of metal grain refinement limit (GRL) at severe plastic deformation (SPD). Relations have been obtained which describe GRL value dependence on SPD rate and temperature. Good agreement between theoretical calculations and experimental data is shown.
