Alloy composition of thin strip Solidification Microstructure Effects of larger, Al-8.5Fe-1.4V-1.7Si and Al-11.7Fe-1.15V-2.4Si alloy. At 20 m / s and wheel line speed and 0.7 x 105Pa jet pressure difference process thin slices of tissue, can see in addition to changes in grain size and a-Al grain accounts for the proportion also vary. The Al-8.5Fe-1.4V-1.7Si alloying degree is relatively low, the alpha -Al grains occupy more volume fraction, while the Al-11.7Fe-1.15V-2.4Si alloy alpha -Al grain volume fraction is relatively small.

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.
