摘要 高温循环变形是结构材料性能降级的主要原因之一.用透射电子显微镜对低活化铁素体/马氏体钢——JLF-1钢低周疲劳样品的微观结构进行了分析,并测试了循环变形前后此钢显微维氏硬度的变化.为了掌握JLF-1钢性能在高温循环变形中的变化机理,依据位错理论,用最小二乘法对高温循环变形后的显微维氏硬度与微观结构进行了回归计算,得到了此钢显微维氏硬度与板条尺寸、位错胞尺寸、位错密度的数值关系. The cyclic softening of a reduced-activation ferritic/martensitic steel, JLF-1, is one of main problems for application. The microstructure of JLF-1 steel after cyclic deformation is analysed by transmission electron microscope and the Vickers hardness is tested. Based on the dislocation theory, the numerical relationship between change in hardness and microstructure of JLF-1 (dislocation density, lath width and dislocation cell size) is given.
