Abstract

Magnesium single crystals, oriented to suppress (0002) basal slip and {101̄2} twinning, were strained in tension parallel to the basal plane, in a <101̄0> direction, at four temperatures (—190°, 25°, 150°, and 286°C) and at two strain rates. Microscopic and X-ray evidence shows that at —190° and 25°C slip occurred primarily on {101̄0} prism planes. At 150° and 286°C, X-ray asterism shows rotations indicating {101̄1} pyramidal slip as the major slip process. The critical resolved shear stresses have been evaluated at each temperature.
