Study of concurrent recovery and precipitation on the mechanical behaviour of Al-Mg alloys with small additions of Cu Medrano, Sebastian


Aluminum-magnesium alloys are commonly used as wrought products in the automotive industry. Cold forming of such alloys leads to strengthening by work hardening but some of this strength can be lost by exposure to elevated temperatures leading to recovery. Such softening by recovery occurs when car body panels are subjected to the industrial paint bake cycle (160-200 C for 30 min). It has been previously shown that small (
