Title: Method for manufacturing aluminum-based casting
Inventor: SEGUCHI TAKESHI
IPC: C22F1/00
Filed: 2001-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing an aluminum-based casting by which residual stress can be reduced. SOLUTION: The method for manufacturing the aluminum-based casting comprises: a solution heat treatment step where an aluminum-based casting of age precipitation strengthening type is heated to a temperature in the solution heat treatment temperature region; a quenching step where the aluminum-base casting is quenched so that it has a low temperature region of <=150 deg.C; and a recuperation step where the aluminum-based casting is cooled slowly and reheated to >=250 deg.C the above low-temperature region by means of recuperation from the inner part.  By carrying out the recuperation step where cooling speed is temporarily decreased in the quenching at T6 treatment for the aluminum- based casting to subject the aluminum-based casting itself to recuperation, thermal stress resultant from the solution heat treatment can be relieved (a kind of tempering treatment) and reduction in strength can be practically prevented and residual stress can be remarkably reduced.
