Molybdenum heavy punch and preparation method thereof
The invention provides a molybdenum heavy punch and a preparation method thereof.The preparation method sequentially comprises the following steps that firstly, a molybdenum source, a lanthanum source, an yttrium source and a cerium source are weighed according to a certain proportion, mixing treatment and sieving treatment are conducted, and molybdenum alloy powder is obtained; secondly, the molybdenum alloy powder is subjected to compression molding treatment, and a pressed blank is obtained; thirdly, the pressed blank is subjected to high-temperature sintering treatment under the reducing atmosphere or inert atmosphere or vacuum condition, and a sintered blank is obtained; and fourthly, the sintered blank is subjected to lathe machining treatment, and the molybdenum heavy punch is obtained. Compared with an existing pure molybdenum heavy punch, the molybdenum heavy punch prepared through the method is fine and uniform in crystal grain, high in recrystallization temperature and good in high-temperature strength and deformation resistance..
