摘要

In this work, several types of deformations (extrusion, one- and two-directional hot pressing) were applied to estimate the influence of regimes of deformations and annealing on characteristics of low-alloying Ru-bearing molybdenum (content of Ru is about 0.3 wt%). This study shows that a combination of extrusion and two-directional hot pressing leads to the formation of a more equiaxial microstructure of the material after annealing. The temperatures of full recrystallization of the studied alloy lie in the range of around 1300–1400°C, depending on the regime of deformation. The median values of grain size in fully recrystallized samples vary from 45 to 75 µm.
