Dedicated to Professor V. I. STARTSEV on the occasion of his 70th birthday The mobility of dislocations in LiF has been measured a t 4.2 and 10 K by means of an etch pit technique. The average velocity of screw dislocations is 2-5 times as large as edge dislocations. The results of the stress and t
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
