马氏体Cr钢亚晶结构的定量表征
Quantitative Characterization of Subgrain Structure of Martensitic Cr Steel
摘要
Abstract
Quantitative characterization of the martensitic Cr steel subgrain was conducted by TEM under different crept states. The crept subgrain'size distribution and their microstructure, as well as their effects on the microhardness were investigated. The results show that the subgrain of the martensitic Cr steel are coarsened under high stress creep, and more coarsened under low stress creep. The coarsened subgrain structure in the crept steel decreased their microhardness and their relationship obeyed the Hall-Petch formula.关键词
