A method for the production of optionally nsta ends, of aluminum alloys treated warmth

摘要

The method of making a heat treated aluminum alloy forging exhibiting reduced "oil-canning" in "oil-canning"-susceptible sections upon machining, including bonding insulation onto an "oil-canning"-susceptible section of an age-hardenable aluminum alloy forging with a bonding agent effective for maintaining a bond during heating for solution heat treatment, solution heat treating the thus-insulated forging, and, with the insulation still on the section, subjecting the solution heat treated forging to a quench for maintaining precipitable components of the alloy in solution in the "oil-canning"-susceptible section, whereby upon machining, said section will exhibit reduced "oil-canning.
