在热冲压中调整定制特性的一种可能性是应用掩蔽概念以防止完全热处理。在这项研究中，不同的概念进行了调查，以使用它们作为一个合适的掩蔽。建立了加热阶段的模拟模型，用于预测最终的显微组织和硬度。实验确定的温度分布用于数值模型。温度分布和硬度的数值结果进行了验证实验研究和非破坏性的硬度测量。模拟的硬度与实测的硬度相当吻合。
One possibility to adjust tailored properties in hot stamping is the application of a masking concept to prevent a complete austenitization. In this study different concepts were investigated in order to use them as a suitable masking. A simulation model of the heating phase was developed for the purpose of predicting the resulting microstructure and hardness. Experimentally determined temperature profiles were used for the numerical model. The numerical results of the temperature profile and hardness were validated by experimental investigations and non-destructive hardness measurements. The simulated hardness is in adequate agreement with the measured hardness.
