曲げ試験における純マグネシウム単結晶の変形挙動

抄録

Pure Mg single crystals with different orientations were subjected to four-point bending tests, and the bending deformation behavior was investigated. With the basal plane parallel to the neutral plane, A and B specimens deformed due to basal slips. Conversely, with the neutral plane and the axis parallel to (1120) and [1100] , C specimen deformed due to {1012} twinning. However, the specimens fractured after a few percent of displacement. E specimen, whose neutral plane and axis were (1010) and [1210] , also deformed due to {1012} twinning. No crack was observed in E specimen since basal slips were activated within {1012} twins.
