| Popis: | Uniaxial compression tests are carried out in the M1 magnesium alloy at 723K under a strain rate of 5.0x10-2s-1 up to a strain of-1.3. Microstructure observation shows that grain distribution is heterogeneous and coarsened grain is observed in all deformation conditions. Mean grain size tends to decrease with increasing strain. Dynamic recrystallization and grain growth are occurred during deformation. (0001) texture which shown at annealed state is weakened with increasing strain, and texture component changed from (0,0) to (24,0) during deformation. The recrystallized grains have no strong preferred orientation about (0001), similar to the grains of growing. |
