An experimental evaluation of the effect of bake hardening on aluminum alloys for automotive lightweight applications is developed through tensile tests and dent tests. All the alloys belong to the 6xxx series and include high formability alloys, improved hemming types and improved bake response alloys. An experimental matrix which contains different time-temperature baking conditions is built, and two pre-strain conditions are considered: no pre-strain and 2% pre-strain. After a data analysis phase performed by means of MATLAB software, the results of the different alloys are compared in terms of mechanical resistance and bake response to identify the materials that are potentially more suitable for certain applications.
