摘要

Using the methods of materials science of physical systems, the structural-phase states and properties of a layer of the T11909 (SAE/AISI) high-speed steel faced on the 4130 (SAE/AISI) medium-carbon steel are studied after its tempering and electron-beam processing. The metal structure in the as-faced and high-tempered states consists of the eutectics and iron-based solid solution grains. It is shown that the e‑beam processing results in a cardinal change of the surface layer morphology and mechanical and tribological properties.
