The fracture behavior of both strain-anneal grown and melt-grown tungsten single crystals of high purity was investigated in the temperature range of 77ยฐK and room temperature. It was found that in the absence of surface defects and weak boundaries crystals of all orientations rupture at room temper
The activation energy, H, the activation volume, w\*, and the frequency factor, Y, for the plastic deformation of niobium at low temperatures (T < 0.2 T,) were derived from creep tests. The values of H and e\* for r\* = 1 kg/mm2 were 0.75 eV and 47bS respectively, decreasing with increase in stress.
