Abstract

A review of results on the pulsed electron beam mixing in Ta/Fe and Mo/Fe systems, which differ in their thermodynamical and thermophysical properties, is presented. As a result of this mixing, a surface layer consisting of an oxide film, amorphous phase, solid solution, and a sublayer of high dislocation density is formed. The corrosion resistance, microhardness, and brittle damage resistance are increased. Thermo- and barodiffusion are found to be main mechanisms of mass transfer.
