Lifetime-compliant process design for the manufacturing of sheet-bulk metal formed components (T08)

在转移项目T08中，子项目C6中开发的寿命模型将被转移到通过板-块金属成形工艺生产的部件，并且对于这些部件，附加热处理旨在增加硬度并影响残余应力状态。将使用高分辨率扫描电子显微镜来表征成形过程引起的韧性损伤，该损伤将被视为使用寿命计算的初始长度。目的是确定热处理损伤补偿的机制和潜力，并应用于演示过程。

Within the transfer project T08, the lifetime model developed in subproject C6 is to be transferred to components, which are produced by a sheet-bulk metal forming process and for which an additional heat treatment is intended to increase hardness and to influence the residual stress state. Highresolution scanning electron microscopy will be used to characterize the ductile damage caused by the forming process, which will be considered as the initial length for the service life calculation. The aim is to determine the mechanisms and the potential for damage compensation by heat treatment and to apply to the demonstrator process.
