Abstract
Electron Microscope Study of Pyramidal Slip {11 2} 〈11 3〉 in Magnesium We have investigated {11 2} 〈11 3〉 pyramidal slip in magnesium whose CRSS exhibits an anomalous dependence on temperature and increases between 270 and 375 K. Typical dislocation configurations were investigated by TEM in various temperature ranges. A model is proposed based on the thermally activated blocking of edge ⅓{11 3} dislocations. The blocking may be due to the dissociation of the ⅓{11 3} dislocation into two ⅙{20 3} partials. Our observations on magnesium are compared with those made on zinc and cadmium by other authors.This publication has 9 references indexed in Scilit:
