摘要：

This experimental work briefly describes the technology of multiple electron-beam melting to produce low-alloy molybdenum alloys with other carbide-forming elements and carbon. Two new alloys described here allow deformation by cold rolling down to a thickness of 0.17 mm. When modifying the Golovin-Sims formula, we show that an alloy with fine (30-200 nm) carbides is hardened during cold rolling much more strongly than an alloy, in which only coarse (>= 1 mu m) carbides are present. The evolution of continuity defects with the deformation during cold rolling is traced.
