本发明提供了一种复合高强韧钼合金及制备方法，以重量份数计，由以下原料制成：氢化钛为5～20份，氢化锆为0～2份，复合还原粉为0.6～1.2份，钼粉为1000份；所述的复合还原粉为碳粉、硼粉和铝粉按照质量比为1:1:1组成的混合粉。本发明的高强韧钼合金的综合性能好，室温抗拉强度大于1200MPa，伸长率大于8.0%。本发明通过还原性更强的C、B、Al元素作为复合还原剂，协同作用，一方面可以与氧结合，能够减少C元素在基体内部的偏析以及与基体生成粗大的第二相的影响，另一方面，能够与基体形成共格或半共格晶体学关系，强韧化作用显著。

The invention provides a composite high strength and tough molybdenum alloy and its preparation method, which is made of the following raw materials by weight parts: titanium hydroxide 5 ~ 20 parts, zirconium hydroxide 0 ~ 2 parts, composite reducing powder 0.6 ~ 1.2 parts, molybdenum powder 1000 parts; The compound reducing powder is a mixed powder composed of carbon powder, boron powder and aluminum powder according to the mass ratio of 1:1:1. The high strength and tough molybdenum alloy of the invention has good comprehensive properties, tensile strength is greater than 1200MPa at room temperature, and elongation is greater than 8.0%. The invention by reducing stronger C, B, Al element as a composite reductant, synergy, on the one hand, can combine with oxygen, can reduce the segregation of C element within the substrate and the substrate to generate gross of the second phase, the influence of, on the other hand, able to form a coherent and matrix or half coherent crystallography relations, strong effect significantly.
