Abstract

Comprehensive analysis of experimental data for the high-temperature mechanical properties of commercial purity tungsten, molybdenum, and their alloys with solid solution, dispersion, and mixed hardening prepared by powder metallurgy with different forms of uniaxial tension is provided. It was established that for materials of this class at high temperature (0.5–0.8 Tm) there is a close correlation between short-term and static stress-rupture strength, and creep resistance, which is described by unified functional dependences that are common for all of the metals and alloys studied.
