Abstract
To understand deformation behavior of non-basal slips in magnesium, tensile tests parallel to basal plane were carried on pure magnesium and Mg-Y alloy single crystals in various temperatures. Pure magnesium single crystals were yielded due to {1122}<1123> second order pyramidal slip under room temperature, while {1011}<1123> first order pyramidal slip were activated above room temperature. In Mg-Y alloy single crystals, first order pyramidal slip was dominant slip mode even at room temperature. {1100}<1120> prismatic slip also observed in Mg-(1.1-1.3)Y alloy single crystals. Mg-Y poly-crystalline sheet specimens were tested in tension to estimate activity of those non-basal slips. In the specimen, those non-basal slips were activated even at yielding in addition to basal slip and frequency of the activity of non-basal slips increase with increasing strain. From the results, we conclude that high ductility of Mg-Y alloy caused from activation of first order pyramidal slip by Y addition.
