High current pulsed electron beam (HCPEB) is an efficient way for materials surface modification. In this paper
we report microhardness distribution of HCPEB-treated metallic materials
including D2 mold steel
Fe-40Al intermetallic and Mg alloys. The extreme temperature and stress fields induced by HCPEB could change the mechanical property in the surface layer and depths beyond that heat-affected zone
hence the property modification of increased depths. The HCPEB treatment could be applied in surface hardening.
