In the case of aluminium, it is relatively easy to perform annealing with an oxygen/acetylene torch. At this stage, any defects caused by deforming the metal can be repaired. Stress relieving, e.g., after welding, can be performed in the range of 200-300 °C. This flux coating will reduce oxidation and help minimize cleanup. Any way of heating the object up above a blue spring (gray color) heat,and slowly letting it cool off will work.
