IFHTSE Global 21: heat treatment and surface engineering in the twenty-first century Part 15 – Progress in surface heat treatment using electron beam surface hardening

Abstract

By using high frequency beam deflection techniques it is possible to carry out highly productive electron beam (EB) surface treatment. As a result of comprehensive investigations about the influence of EB parameters on structure and properties of the material in connection with EB hardening of steels and cast irons over the last 25 years, very interesting industrial applications are available now. The paper deals with the state of the art in this field.
