Method for making a heat treated aluminum alloy article

摘要

A method for making a heat treated aluminum alloy article, including the steps of bonding insulation onto selected areas of the article with a bonding means for maintaining a bond during heating for solution heat treatment, solution heat treating the thus-insulated article, and, with the insulation still on the article, subjecting the solution heat treated article to a quench for maintaining precipitable components of the alloy in solution and, subsequent to the quench, age-hardening the article.
