Abstract
Phase-separation process is essential phenomenon owing to influence on quality of alloy. Miscibility gap was found on phase diagram of Cr-W alloy, however other things of Cr-W alloy haven't been studied after that. Therefore the aim of this study is to prepare nonequilibrated alloy under the miscibility gap by shock compression method, and to study grain size dependence on it. W powder of average grain size between 1μm to 8μm mixed Cr powder of 10μm grain size is put pressure on 42GPa using a one-stage powder gun. As a result, the smaller W grain size is, the more Cr-W alloy. And in the case that W powder is small to 0.6μm and enough specific surface area in mixed powder, nearly homogeneous Cr-W alloy prepared. Fluid Cr alloy with W melted as high temperature concentrate on surface of grains.
