Flexural strength was measured on high‐purity selenium glass over a wide range of temperatures and strain rates. This glass exhibited wide variations in strength and other properties as temperature and strain rate varied. The strength of glassy Se increased significantly with temperature over 2 temperature ranges, and the highest strength occurred at temperatures just below the glass transition region. The flexural strength also increased with strain rate at all temperatures investigated. Substantial evidence of crack blunting was found in tests at 25°C.
