This project deals with experimentally identifying strategies to design damage-tolerant DP microstructures. For this purpose, the most important parameters, namely volume fraction, strength, grain size, and morphology of ferrite and martensite, will be varied systematically and independently. This will be approached in an iterative manner by thermodynamic calculations, combinatorial synthesis, testing of the mechanical properties, and damage tolerance as well as high resolution microstructure characterization. Thereby identified design strategies will be subsequently upscaled and validated in the process chain of the TRR 188.

本项目涉及实验识别策略，设计损伤容限DP微结构。为此，最重要的参数，即体积分数，强度，晶粒尺寸，铁素体和马氏体的形态，将系统地和独立地变化。这将通过热力学计算、组合合成、机械性能测试、损伤容限以及高分辨率微观结构表征以迭代方式接近。因此，确定的设计策略将随后在TRR 188的过程链中升级和验证。
