Repeated Shot Treatment to Increase the Fatigue Strength of High-Strength Steel Parts

  • Published:
Russian Engineering Research Aims and scope

Abstract

The effectiveness of repeated shot treatment in increasing the fatigue strength of high-strength 30ХГСН2А steel parts is established experimentally. Repeated shot treatment not only restores the initial life but increases it significantly.
