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转移到由薄板-大块金属成形工艺生产的部件上，并对其进行额外的热处理以提高硬度并影响残余应力状态。高分辨率扫描电镜将用于表征成形过程中造成的延性损伤，这将被视为计算使用寿命的初始长度。目的是确定机制和潜在的损害赔偿的热处理，并适用于示范过程。

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.
