摘要
采用Gleeble2000热力学模拟试验机对Mg-10Gd-3Y-Zr镁合金进行了不同变形条件下的单向热压缩试验.研究变形温度、变形程度、变形速率等变形条件对合金显微组织及力学性能的影响,优化成形工艺参数。结果表明,对于Mg-10Gd-3Y-Zr镁合金,合理的等温成形应在较高的变形温度(410~440℃),较低的变形速率(0.001~0.01 s^(-1)),较大的变形程度(≥25%)下进行。
Unidirectional compression experiment under different deformation conditions was carried out by Gleeble2000. It was studied that how deformation condition （deformation temperature, deformation extent and deformation velocity） influenced microstruc- ture and mechanical property of Mg-10Gd-3Y-Zr magnesium alloy. The result indicates that the optimum deformation condition of Mg- 10Gd-3Y-Zr magnesium alloy is higher deformation temperature （410 -440 ℃ ）, higher deformation extent（≥ 25 % ） and lower deform- ation velocity（0. 001 - 0.01 s^-1 ）.
