金属铝及其合金住宇航、冶金、机械、电子、石油化工等工业部门得到了广泛的应用。随着科学技术的发展,对钼及其合金的性能又提出了更高的要求。近年来人们十分重视稀土元素对钼合金性能影响的研究。据报导铈与氧亲和力较大,对钼及其合金有很好的脱氧作用,使延性得到改善,而加入稀土氧化物效果如何,这是本文研究的 Aluminum and its alloys live in aerospace, metallurgy, machinery, electronics, petrochemical and other industrial sectors have been widely used. With the development of science and technology, the performance of molybdenum and its alloys put forward higher requirements. In recent years, people attach great importance to rare earth elements on the performance of molybdenum alloys. It has been reported that cerium has a large affinity with oxygen and a good deoxidation effect on molybdenum and its alloys, resulting in an improvement in ductility. However, the effect of adding a rare earth oxide is what this article studies
