METHOD FOR PRODUCING LIQUID PHASE SINTERED ALUMINUM ALLOY MEMBER, AND LIQUID PHASE SINTERED ALUMINUM ALLOY MEMBER

WIPO Patent Application WO/2015/045780

A1

A method for producing a liquid phase sintered aluminum alloy member, which comprises: a molding step wherein a starting material powder containing an aluminum alloy powder that contains at least one element selected from among Si, Mg, Cu and Zn with the balance made up of Al and unavoidable impurities is molded, thereby obtaining a molded body; a sintering step wherein the molded body is subjected to liquid phase sintering, thereby obtaining a sintered body; a softening step wherein the sintered body is subjected to a heat treatment, thereby obtaining a softened material; a straightening step wherein the softened material is subjected to sizing, thereby obtaining a straightened material; and an aging step wherein the straightened material is subjected to a heat treatment, thereby obtaining an aged material in which a precipitate is present.
