Effect of some structural parameters on high-temperature crack resistance of tungsten

  • 1. AN Ukrainskoj SSR, Kiev. Inst. Problem Prochnosti

Description

The paper presents results of physicomechanical studied in high-temperature crack resistance of tungsten produced by powder metallurgy methods. It is shown that at high temperatures (>2000 deg C) a structure is formed in the material and fails at stresses independent of temperature. It is found that high-temperature tungsten crack resistance is affected neighter by changes in the effictive grain size, nor by appearance of grain-boundary microcraks in the material under high-temperature action
