Laser Heat Treatment
treat precise areas of metals without involving the entire workpiece. With laser heat treatment, the mass of the material being processed is generally sufficient for rapid heat removal or "quenching ". The enhanced mechanical properties resulting from laser heat treatment depend upon the specific...

natural or artificial aging can be significant. In addition, distortion and residual stresses can be introduced during quenching from the solution heat-treatment cycle. These induced changes can be removed by deforming the metal (for example, stretching). Wrought aluminum alloys are also strengthened...
