ABSTRACT:
A method of manufacturing sintered Al-Si series alloy parts having complex configurations such as scroll shaped parts wherein Al-Si series alloy powder solidified via rapid cooling prepared by adding effective components such as Si, Cu, Mg, Fe, Mn, Zr and Ce to Al is compression molded, the molded body is sintered by heating via an electrical current conduction in a form of a plasma discharge and then the sintered body is worked by pressing, thereby the parts having complex configurations of light weight, high mechanical strength and toughness is manufactured with a simple installation and reduced processing manhours, and with a high efficiency and at a low cost.
