Abstract

Mechanical properties of deformed rods fabricated from a cast niobium alloy of grade 5VMTs-2 and powder molybdenum and tungsten alloys of grades M-MP, MV-2-MP, and V-5-MP are studied in the temperature range of 120–2000°C. It is shown that the behavior of the temperature dependences of the mechanical properties of the rods in the lengthwise and widthwise directions is similar. The ductility characterstics differ substantially in the range of the brittleness threshold. By increasing the degree of deformation the anisotropy of the mechanical properties is diminished and the level of the ductility is increased.
