Modification of the structure and mechanical properties of a hard alloy using a high-power electron beam

Research output: Contribution to journalArticle

Abstract

The hard alloy consisting of tungsten carbide and 110G13L steel is subjected to a high-power beam of low-energy electrons and then investigated by optical metallography, X-ray structural analysis, and transmission diffusional microscopy. Pulsed electron bombardment leads to the formation of a quasi-periodic mesostructure over the whole volume of the composite. The resulting material consists of a laminar alternation of the initial structure along with nanometer and submicron structures affecting the outcome of deformational and polymorphous transformations in the hardener and the matrix. Such electron bombardment allows high hardness, strength, and plasticity to be obtained simultaneously in hard alloys.
