AbstractHigh current pulsed electron beam (HCPEB) is a fairly new technique for surface modifications. The present contribution reviews some recent insights on the microstructure modifications encountered at the top surface of HCPEB treated (NiTi and FeAl) intermetallics. In particular, the potential of the technique for structure modifications associated with the use of the pulsed electron beam under “heating” and “melting” conditions is highlighted. The interesting surface modifications include the creation of an homogeneous protective layer under the melting mode while thermal stresses under the heating mode can induce surface hardening and stress enhanced rapid solid state alloying.

Low energy high current pulsed electron beam (LEHCPEB) is a fairly new technique for surface modifications, including hardening, alloying and formation of metastable phases as well as improvement in wear and corrosion properties. 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.
