研究了一种Fe-1.4%Cr-1%C珠光体钢在不同条件下的超快速感应加热淬火组织和硬度。形成了由两种不同类型的马氏体(高孪晶或含有高位错密度)组成的纳米级层状组织,在0.5s加热至1223K后淬火,获得了最大硬度。电子能量损失谱分析表明,在srihq工艺实现的非均匀溶质分布中,两种不同类型的马氏体的形成取决于局部溶质浓度。
Microstructures and hardness of a Fe–1.4%Cr–1%C pearlitic steel processed by super-rapid induction heating-and-quenching (SRIHQ) under various conditions have been investigated. A nano-scaled laminated microstructure composed of two different types of martensite (highly-twinned or containing a high dislocation density) was formed and the maximum hardness was obtained by heating to 1223K in 0.5s and quenched. Electron energy loss spectroscopy indicated that the two different types of martensite were formed depending on the local solute-concentration in the non-uniform solute-distribution realized by the SRIHQ-process.
