Abstract
In order to overcome the inferior thermal fatigue (TF) properties of FeCrB alloy, FeCrBTi alloy containing in-situ formed particles has been developed. This study systematically investigated the enhancement mechanism induced by in-situ particles through the TF experiment. Results demonstrated in-situ particles not only directly alter the crack propagation path but also refine the microstructure, thereby contributing to stress reduction and improving mechanical properties. Furthermore, in-situ particles promote the formation of a compact and adhesive oxide scale. Therefore, the TF properties of FeCrBTi alloy are 3.1 times higher compared to FeCrB alloy. This research shed a novel light on the improvement of TF resistance of tool steels.
