JLF-1钢高温循环变形后硬度与微观结构的数值关系
Numerical relationship between hardness and microstructure of JLF-1 steel after cyclic deformation
摘要
Abstract
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.关键词
