Cracking during the formation of surface alloys based on chrome by a low-energy high-current electron beam
The results of a crack formation of a Cr-Zr surface alloy formed by a low-energy high-current electron beam are presented. The morphology and elemental composition of the surface alloy in the area of crack formation have been investigated. It is shown that cracks propagate along the surface regardless of the location of pits and grooves, which indicates a greater dependence of cracking on internal stresses, and not on roughness or other structural factors. It was found that the distribution of elements affects the cracking of the surface alloy: the elemental composition in the area of crack formation is close to equiatomic.
