| 摘 要： | 采用自约束热疲劳试验方法，在相同的热处理条件下，对比研究了8407，4Cr5MoSiV1钢的纵横向热疲劳特性，观察分析了两种钢的热 形貌及深度，并选择典型试样进行扫描电镜分析，结果表明，8507钢比4Cr5MoSiV1钢的碳化物颗粒较小，而且分布均匀，从而表现出较好的热疲劳性能，尤其是4Cr5MoSiV1钢的横纵向热疲劳性能差异较8407钢大，即8407钢的各向同性要优于4Cr5MoSiV1钢，与两种钢的横纵向冲击韧性的比值相对应。 |

| Abstract: | The thermal fatigue behavior in transversal and longitudinal directions in 8407 steel and 4Cr5MoSiV1 steel after the same heat treatment is studied with self restricting test method. The crack morphology and depth in both steels are analyzed, some typical specimens are also observed by SEM. It is shown that, compared to 4Cr5MoSiV1 steel, 8407 steel has finer and more dispersed carbide, therefore better thermal fatigue resistance. The difference in thermal fatigue behavior between transversal and longitudinal directions in 8407 steel is smaller than that in 4Cr5MoSiV1 steel, corresponding to the different ratio of impact properties in the longitudinal direction to the transversal direction between both steels. |
