Process of treatment of a precipitation hardenable Al-Mg-Si-alloy

摘要

The process relates to a thermo-mechanical treatment of a precipitation hardenable Aluminium-Magnesium-Silicon electrical conductor alloy, after rapid cooling for keeping alloying elements in solution. The alloy is rolled during quenching from a temperature range between hot working temperature and quenching temperature, down to more particularly the alloy is rolled during a quenching operation after hot rolling, to produce wire rods which need no solution treatment before further drawing into wire and where necessity of aging is strongly reduced or eliminated.
