Abstract
A method for producing a liquid phase sintered aluminum alloy member, includes: a compacting process of compacting a raw material powder containing an aluminum alloy powder containing at least one element selected from Si, Mg, Cu, and Zn, with the balance being Al and unavoidable impurities to form a green compact; a sintering process of subjecting the green compact to liquid phase sintering to give a sintered body; a softening process of subjecting the sintered body to a heat treatment to give a softened material; a straightening process of sizing the softened material to give a straightened material; and an aging process of subjecting the straightened material to a heat treatment to give an aged material in which precipitates are formed.
