中文摘要：
研究了不同挤压温度对Mg-2.0Zn-0.3Zr-0.9Y新型镁合金组织和性能的影响。结果表明,降低挤压温度,Mg-2.0Zn-0.3Zr-0.9Y合金的平均晶粒尺寸得到显著细化,合金的屈服强度和抗拉强度得到大幅提高,而延伸率变化不大。随着挤压温度的降低,{10ī2}织构强度不断增强,{0002}基面环形织构强度减弱。Mg-2.0Zn-0.3Zr-0.9Y合金的力学性能不但受到组织平均晶粒大小的影响,还受到织构分布的影响。挤压温度为330℃时可获得细小的组织和优良的力学性能,平均晶粒尺寸达到1.76μm,合金抗拉强度达到323MPa,屈服强度为309MPa,延伸率为21.92%。
英文摘要：
The effects of extruding temperatures on the microstructures and mechanical properties of the Mg-2.0Zn-0.3Zr-0.9Y magnesium alloy were investigated. The results show that the grain size of Mg-2.0Zn-0.3Zr-0.9Y alloy is significantly refined by decreasing the extruding temperature. Meanwhile the tensile strength and the yield strength are greatly enhanced, but the elongation is increased little. With the decrease of extruding temperature, the intensity of {10 ī 2} texture is enhanced, while that of the {0002} basal ring type texture is decreased. The mechanical properties of the alloy are not only related with the average grain size, but also with the texture. Mg-2.0Zn-0.3Zr-0.9Y magnesium alloy extruded at 330 °C possesses a fine grain size of 1.76 μm on average and good mechanical properties including the elongation of 21.92%, the yield strength of 309 MPa and the tensile strength of 323 MPa.
