Abstract
The treatment of 20Cr13-grade hardened steel (0. 2% C, 13% Cr) with an electron beam whose energy density is 10-30 J/cm2 results in an increase in the fatigue life by a factor of 1. 9. The irradiated surface is investigated by scanning electron microscopy; substantial refinement of the grain structure and a change in the Cr content in the surface layer are revealed.
