Analysis of Metals Surface Structure Modifications Induced by High Current Pulsed Electron Beam (HCPEB) under the “Heating” and “Melting” Modes

Abstract:

High current pulsed electron beam (HCPEB) is a fairly new technique for surface modifications, including hardening, alloying and formation of metastable phases. The present contribution gives some new insights on the microstructure modifications encountered at the top surface of HCPEB treated metals. In particular, the potential of the technique for structure modifications associated with the use of the pulsed electron beam under “heating” and “melting” conditions are highlighted.
