| 说明书摘要 | The present invention relates to a process for preparing a powdered tungsten-aluminum alloy, in which the powdered tungsten and aluminum as starting materials is mechanical alloyed at normal temperature to provide the tungsten-aluminum alloy. The process of this present invention is simple and easy and the device used is simple to handle. The process is carried out at room temperature, and is suitable for preparing an alloy of metals wherein there is large disparity between melting points and densities of the metals, which alloy could not be prepared by the known smelting process. | ||
