本发明公开了种界面强化钼合金及其制备方法，钼合金包括以下质量百分比的成分：85％-98％Mo、0.5％-15％活性金属元素、0.1％-5％碳化物以及0.1％-5％稀土金属氧化物；所述钼合金具有钼-活性金属相-钼的强化界面。本发明通过活性金属分离钼-钼弱结合界面，形成"钼-活性金属相-钼"的强化界面，同时利用超细/纳米碳化物与稀土氧化物的均匀复合弥散分布形成的大量微观界面吸收中子辐照产生的点缺陷，从而提高钼合金界面结合强度与韧性，并因此改善抗辐照脆化性能。 The invention discloses an interface reinforcing molybdenum alloy and a preparation method thereof. The molybdenum alloy is prepared from the following ingredients in percentage by mass: 85 to 98 percent of Mo, 0.5 to 15 percent of active metal elements, 0.1 to 5 percent of carbides and 0.1 to 5 percent of rare earth oxides. The molybdenum alloy has a molybdenum-active metal phase-molybdenum reinforcing interface. Through the active metal separation molybdenum-molybdenum weak combination interface, the molybdenum-active metal phase-molybdenum reinforcing interface is formed; meanwhile, a great number of microscopic interfaces formed by uniform composite scattering distribution of ultrafine/nanometer carbide and rare earth oxide are utilized for absorbing point defects generated by ne
