The subproject aims at understanding the interactions between hardening/softening and damage initiation at the interface between matrix and non-metallic inclusions during hot forming and to derive a coupled model for the microstructure and damage evolution based on the findings. The model shall capture the influence of the measures influencing the damage evolution during hot working and hence be used within the main project for the design of hot working processes with controlled damage evolution. For the development and calibration of the model, hot tensile tests with notched specimens as well as methods of physical simulation are used.

该子项目旨在了解热成形过程中基体和非金属夹杂物之间界面处的硬化/软化和损伤引发之间的相互作用，并根据研究结果推导出微观结构和损伤演化的耦合模型。该模型应捕获影响热加工过程中损伤演变的措施的影响，因此可在主项目中用于设计具有受控损伤演变的热加工工艺。对于模型的开发和校准，热拉伸试验与缺口试样以及物理模拟的方法。
