| Abstract: | Ball milling is a new process for making nanocrystalline materials. This process is very simple and has the advantage of wide applications. The grain size changes of four W 80 X 20 alloys during ball milling process are compared.Through the analysis of the melting points of different alloys,the plastic deformation diffusion double mechanisms for making nanocrystalline in W alloys are proposed. |
