Molybdenum Rhenium Alloy is a refractory alloy, so it is generally prepared by powder metallurgy or vacuum melting. Both methods have their own advantages and disadvantages.

The molybdenum-rhenium alloy ingot prepared by vacuum smelting can well control the impurity content, especially the gas element content is significantly reduced, and the intermediate phase is not easy to precipitate, which is beneficial to the subsequent processing of Molybdenum Rhenium Alloy. However, the preparation of this method The grains of molybdenum-rhenium alloy ingots are usually relatively coarse, and the size distribution is uneven, which increases the difficulty of alloy blanking.
Compared with the vacuum smelting method, the process of preparing Molybdenum Rhenium Alloy by powder metallurgy is relatively simple, the cost is low, and it is relatively easy to realize industrialization. Therefore, the products currently on sale are almost all produced by powder metallurgy. But powder metallurgy It is not easy to control the impurity content in the alloy ingot. Generally, the sintered ingot can be well controlled by vacuum melting.
