Title: Manufacture of aluminum alloy with high workability
Inventor: KIMURA HIROMASA
IPC: C22F1/04
Filed: 1989-01-11
Abstract: PURPOSE:To obtain an Al alloy having high workability without losing high brightness characteristics by successively subjecting an Al alloy ingot of Al-Mg type to heating up to a specific temp., to slow cooling, to hot and cold workings under specific conditions, and further to softening heat treatment. CONSTITUTION:An Al alloy ingot of Al-Mg type is heated up to 480-520 deg.C to undergo homogenization. At this time, when this ingot is heated up to a temp. higher than 520 deg.C and cooled, Mg is precipitated at the grain boundary and dissolution is brought about, and, when the temp. is lower than 480 deg.C, the entering into solid solution of Fe and Si becomes insufficient. Subsequently, the above ingot is reheated up to 480-520 deg.C and cooled slowly down to 380-420 deg.C to prevent the precipitation of Fe and Si, and, at this time, when the temp. is lower than 380 deg.C, cold draft in successive rolling is increased and, as a result, problems occur. The above ingot is subjected to hot working at 85-98% draft at 180-260 deg.C finishing temp., by which crystalline grains are refined and the occurrence of nonuniform luster in stripes can be prevented. Then, cold working is applied to the above at 80-85% cold draft, but high extensibility after softening treatment cannot be obtained when this cold draft is beyond the above range. Further, heating up to 390-410 deg.C is carried out to perform softening treatment.
