Abstract

It was found by optical microscopy and TEM methods that high rate hardening an austenitic steel from liquid state leads to intensive structure and phase transformations when the surface was treated by low energy high-currents electron beam. The structure transformations were occurred when the grain structure (type of grain boundaries) was changed, subgrains formation inside the grains took place with cell disoriented dislocation substructure, and internal stress fields and deformation microtwins formations were occurred, too. The fine and quasi-amorphous particles of Cr and Ti carbides were formed in the process of phase transformations as well as α-phase ones throughout the grain and subgrain boundaries. The grain and integranular structure modification, as well as phase transformations, lead to the steel surface layers microhardness increasing.
