Abstract
Impact on the structure and properties of the materials by methods of severe plastic deformation (SPD) is an actual problem of mechanical engineering. Computer Simulation in the package Deform been made to analyze the impact of this method SPD on the microstructure of materials Waspalloy and steel42CrMo4. Average grain size was estimated by the model «Johnson – Mehl – Avrami – Kolmogorov» (JMAK) in the test points at each step of the process SPD. The modeling found that after one full cycle of deformation of the average grain size is significantly reduced.
