摘要
通过光学显微组织观察、X射线衍射、透射电镜表征和拉伸力学性能测试等方法研究了热处理工艺对Mg-8.12Gd-1.82Y-0.35Zr合金环形件显微组织和力学性能的影响。研究结果表明:T5处理和T6处理均可以大幅提高环形件的强度,并且经过两种不同工艺处理的环形件,其强度无显著差异,但相比之下T6处理可以显著提高合金的伸长率。
The effects of heat treatment process on the microstructure and mechanical properties of Mg-8.12Gd-1.82Y-0.35Zr alloy annular forging were studied by using optical microscopy,X-ray diffraction,transmission electron microscopy and mechanical testing.Results show that,both T5 and T6 treatment can obviously improve the strength of the annular forging.The annular forging treated by both processes exhibits similar strength,but T6 treatment can significantly improve the elongation of the alloy.
