DEFORMATION AND FRACTURE OF MAGNESIUM BICRYSTALS. Technical Report No. 6
Technical Report
·
OSTI ID:4273427
The effects of piled-up arrays of dislocations on inducing slip, twinning, and fracturing in magnesium bicrystals were investigated. A series of variously oriented bicrystals of magnesium having a vertical grain boundary was prepared and tested in tension. It was found that piled-up arrays of dislocations at the grain boundary could, under appropriate conditions, induce slip, twinning, and cracking. The results that were obtained substantiate, at least qualitatively, the general dislocation mechanism for transmission of strain across grain boundaries and the Petch-Stroh concept of fracturing.
