摘要：

Versions are demonstrated for improving the impact-abrasive wear resistance of powder alloy steels due to reducing residual porosity. Regression equations and graphical dependences are presented for the effect of production parameters for specimen preparation by methods of hot dynamic compaction, surface plastic deformation and twofold compaction on residual porosity and wear resistance.
