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.

揭示原位粒子对铁铬硼合金热疲劳性能的影响

为了克服铁铬硼合金较差的热疲劳（TF）性能，开发了含有原位形成颗粒的铁铬硼钛合金。本研究通过 TF 实验系统地研究了原位颗粒诱导的增强机制。结果表明，原位颗粒不仅直接改变了裂纹的扩展路径，还细化了微观结构，从而有助于降低应力和改善力学性能。此外，原位颗粒还能促进形成致密且具有粘附性的氧化物鳞片。因此，FeCrBTi 合金的 TF 性能是 FeCrB 合金的 3.1 倍。这项研究为提高工具钢的抗 TF 性能带来了新的启示。
