Behavior of Al-Mg alloy subjected to thermal processing

In the paper are shown the experimental results obtained for aluminum alloy, after application of the heat treatments by quenching solution and artificial ageing. The purpose of quenching solution treatment is to decrease the hardness and improve the machining for industrial parts made from this material. By artificial ageing treatment, the Al-Mg structure is modified, the hardness increase to the values necessary for a long exploitation of the parts.
