铝合金满足日益增长的轻量化应用需求，并且是完全可回收的。高强度铝合金的使用为取代与安全相关的钢部件提供了机会。目前，这些合金的使用受到限制，因为它们的低成形性和高回弹在室温成形时。使用具有本地适应性材料特性的定制坯料是克服这些限制的一个机会。通过局部热处理，区域局部软化，从而在成形过程中可以避免关键区域的裂纹。目前，具有定制性能的毛坯应用并不广泛。其中一个原因是由于热应力引起的部件变形，这使得处理热处理板更加困难。本研究的目的是识别和减少热引起的部件变形。因此，本文研究了初始材料条件、板材厚度以及激光光斑尺寸对变形行为的影响。
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.
