Abstract :
The results of investigation of the mechanism of hardening of previously hardened carbon steel (0.45–1.2 % C) by microsecond low — energy high-current electron beam are presented. It is shown that maximum hardening is reached beyond the thermal action zone and is caused by effect bipolar stress wave on martensite. Intense deformation processes initiated in region of penetration of this wave leads to the formation of strongly fragmented structure with high level of defectivity and anomalously high values of microhardness.
