Hot pressing method although can effectively improve the density of the rapid hardening slice powder, but due to the rapid hardening slice heat ultrafine microstructure of aluminum alloy powder body approximately in to static pressure state, under the limited high loading stress condition, high temperature die impossible realization of powder fully densified. The density and properties of heat resistant aluminum alloy materials can be improved by the plastic deformation process such as extrusion and die forging. The project intends to by hot extrusion plastic deformation technology to improve the performance of the material by of different billet temperature, die temperature, extrusion ratio and extrusion speed and the influence of parameters on the material properties of plastic deformation, and ultimately determine the best extrusion technology.
