引言钼的熔点高(2622℃),在高温下具有高的抗张强度、蠕变强度以及良好的耐热震性。膨胀系数低(4.6×10~(-6)/℃),同时对液态金属Na、K、Bi、Cs等及其熔盐有较好的抗蚀性、热中子俘获截面也比较小(2.4靶/原子),国外几种钼合金性能示于表1。由于钼合金有上述性能,因此,它除广泛地应用于宇航工业、原子能工业外,尚有电子、化学和冶金工业等部门。随着我国社会主义事业的飞速发展,对钼及其合金的研
Introduction Molybdenum has a high melting point (2622 ° C), high tensile strength, creep strength and good thermal shock resistance at high temperatures. Low coefficient of thermal expansion (4.6 × 10 -6 / ℃), good corrosion resistance to liquid metals such as Na, K, Bi, Cs and their molten salts, and their thermal neutron capture cross section is relatively small (2.4 Target / atom), several foreign Molybdenum alloy properties are shown in Table 1. As the above-mentioned properties of molybdenum alloy, it is widely used in aerospace industry, atomic energy industry, there are the electronics, chemical and metallurgical industries. With the rapid development of our socialist cause, research on molybdenum and its alloys
