Abstract
The experimental work briefly describes the technology of multiple electron beam melting, which allows to obtain low-alloy molybdenum alloys with other carbide-forming elements and carbon. Two new alloys described in the work allow deformation by cold rolling up to a thickness of 0.17 mm. Based on the modified Golovin—Sims expression, it is shown that an alloy with dispersed carbides (size 30-200 nm) is strengthened during cold rolling much stronger than an alloy in which only large (≥1 microns) carbides are present. The evolution of continuity defects during cold rolling with an increase in the degree of deformation is traced.
