研究了热挤压加工对铸造AM50镁合金组织及力学性能的影响。结果表明,热挤压加工后,AM50镁合金出现沿挤压方向的条带状组织,由于发生了动态再结晶,合金的晶粒细化,从而提高了拉伸性能;断裂机制为塑性和韧性混合断裂模式。
The effect of hot extrusion process on the microstructure and mechanical properties of cast AM50 magnesium alloy was studied. The results show that, after hot extrusion, AM50 magnesium alloy strip along the extrusion direction of the organization, due to the occurrence of dynamic recrystallization, the grain refinement of the alloy, thereby enhancing the tensile properties; fracture mechanism for plasticity and toughness Mixed fracture mode.
