| Zusammenfassung: | In general, deformation behavior of magnesium in compression is different from tensile.
To investigate deformation behavior of magnesium single crystals, c-axis compression was
performed. 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 is bigger than that of a-axis tensile. {10-13} twin and
{11-24} twin occurred at 77293K and 77473K respectively. Fracture surface at 77293K was
{11-24} and at 473K was {11-22}. |
