Abstract
The authors establish the temperature relationship of the strength and plastic properties of tungsten and tungsten-base alloys taking into consideration the statistical parameters of the spread caused by structural and technical factors and a quantitative determination of the influence in tension of dispersion hardening of tungsten with refractory particles of hafnium and yttrium oxides. The observed dip in plasticity in the dispersion-hardened tungsten alloys does not contradict the mechanism of high temperature embrittlement of commercially pure tungsten.
