To investigate deformation behavior of magnesium single crystals by non-basal slips and twins, c-axis compression and a-axis tension tests were performed in the range of 77K-573K. The crystals were yielded by second order pyramidal slip, and the yield stress shows anomalous temperature dependence (increased with increasing temperature) between 203K and 293K. Yield stress of c-axis compression was bigger than that of a-axis tensile. In compression, fracture surface were (11 4) under 293K and were {30 4} above 373K, and fracture strain was smaller than the case of tension test. {10 1}-{10 2} double twin were activated at higher temperature and the crystal, therefore, fractured along the twin interface., http://www.scientific.net/MSF.654-656.699}, pages = {699--702}, title = {Deformation Behavior of Magnesium Single Crystal in c-Axis Compression and a-Axis Tension}, volume = {PRICM7}, year = {2010}, yomi = {キタハラ, ヒロモト} }
