Laser Assisted Procedure for Local Thermal Manipulation of Aluminium Alloys

Abstract:

This study presents experimental results of an approach consisting of local heating of aluminium alloy structures with the purpose of introducing a local change of material properties. Such modification can be precisely induced using a laser source, as detailed in this study. By a laser induced pre-treatment, the material properties are locally changed so that influencing the material flow is possible. It is therefore possible to improve deep drawing of high strength aluminium alloys. This technique can also be applied to thin-walled section aluminium tubes in order to act as local triggering of the deformation process reducing peak loads and inducing energy favourable folding modes. This study presents preliminary results of temperature, heating cycle and laser parameters influence in material properties and microstructure of a selected 6060-T5 aluminium alloy.
