以0.47%Y₂O₃、0.6%Y₂O₃、0.8%Y₂O₃、1.0%Y₂O₃四种不同加入量，掺杂制备出MoO₂粉末，还原出Mo-Y合金粉末，通过冷等静压成形得到坯体，在氢气气氛中以最高烧结温度为1850℃、保温时间为6h的工艺烧结得到Ø17mm烧结棒坯，进而锻造、拉拔至Ø0.18mm的丝材。在拉拔过程中，四种Mo-Y合金分别在Ø8mm、Ø2.75mm、Ø1.8mm、Ø1.05mm和Ø1.8mm取样，测量室温力学性能，并对最终产品Ø0.18mm进行断口分析。得出了Y₂O₃含量对Mo-Y合金的室温力学性能和断口形貌的影响规律。

^With 0.47%Y₂O₃, 0.6%Y₂O₃ 0.8%Y₂O₃, 1.0%Y₂O₃ in four different dosages, MoO₂ powder is prepared by doping, Mo-Y alloy powder is reduced, and the green body is obtained by cold isostatic pressing. Ø17mm sintered bar billet is sintered in a hydrogen atmosphere with a maximum sintering temperature of 1850℃ and a holding time of 6h, which is then forged and drawn to a wire of Ø0.18mm. During the drawing process, four Mo-Y alloys were sampled at Ø8mm, Ø2.75mm, Ø1.8mm, Ø1.05mm, and Ø1.8mm to measure the mechanical properties at room temperature, and perform fracture analysis on the final product Ø0.18mm. The effect of Y₂O₃ content on the room temperature mechanical properties and fracture morphology of Mo-Y alloy was obtained.
