温度对AZ80镁合金等通道转角挤压组织性能的影响
温度对AZ80镁合金等通道转角挤压组织性能的影响
AZ80 Mg alloy was processed at 320°C and 200°C by equal channel angular pressing. At 320°C, the grain size was decreased at previous two passes and then increased in the subsequent passes. At 200°C, both the density of dislocation and twinning were increased at previous two passes with the hardness dramatically increased. After 4 passes with route Bc, the grain size was refined to 200nm in most of areas, but the hardness slightly increased due to the interaction of grain refinement strengthening and texture softening.

Abstract
AZ80 Mg alloy was processed at 320°C and 200°C by equal channel angular pressing. At 320°C, the grain size was decreased at previous two passes and then increased in the subsequent passes. At 200°C, both the density of dislocation and twinning were increased at previous two passes with the hardness dramatically increased. After 4 passes with route Bc, the grain size was refined to 200nm in most of areas, but the hardness slightly increased due to the interaction of grain refinement strengthening and texture softening.
