| 内容記述 | The change in structure of 9Cr-1Mo steel caused by heat-treatment after cold working was investigated on the basis of Vickers hardness test, X-ray diffraction, and SEM observation. Many precipitates of chromium carbide were observed in the surface of cold-rolled specimens. By the heat-treatment at 700℃, the growth of grain and precipitate were observed. We measured Vickers hardness, HV, and the half-value width of X-ray diffraction peak for the specimen heat-treated after the cold-rolling. By heat-treatment at 100-200℃, HV slightly increased, but the half-value width was nearly constant. At the heat-treatment temperature at 200-500℃, Vickers hardness, HV, increased slightly, and the half-value width decreased. These phenomena result from the diffusion of interstitial impurities around dislocations. At 500-700℃, both HV and the half-value width decreased. The decrease in HV and the half-value width is caused by recrystallization, that is, large decrease in dislocation density. | |||||
