Aluminum alloys fulfill the growing demands for lightweight applications and are completely recyclable. The use of high-strength aluminum alloys offers the opportunity to replace safety-relevant steel components. Currently, the use of these alloys is limited due to their low formability and high springback during forming at room temperature. The use of tailored blanks with locally adapted material properties is one opportunity to overcome these limitations. By local heat treatment, zones are locally softened and thus crack critical areas during forming can be avoided. At present, blanks with tailored properties are not used extensively. One reason for this is component distortion due to thermal stress, which makes handling the heat-treated sheets more difficult. Aim of this study is the identification and reduction of thermally caused component distortion. Therefore, in this paper the influence of the initial material condition, the sheet thickness as well as the laser spot size on the distortion behavior is investigated.
