对一定冷变形00Cr22Ni5Mo3N双相不锈钢再结晶退火后的显微组织进行了研究.结果表明:退火温度从1000℃开始依次增加50℃至1200℃,通过XRD的检测,确定了试样组织由β、γ两相组成,在再结晶退火温度下没有新相产生;经退火处理后得到大小均匀的等轴晶;在较高退火温度下的铁素体的体积分数明显比在较低退火温度下的铁素体的体积分数要高;较低退火温度比较高退火温度的品粒细化的效果要好.在较高退火温度下导致晶粒的长大;不同的再结晶退火温度与试样的显微硬度表现出复杂关系.

The microstructure of cold deformation 00Cr22Ni5Mo3N duplex stainless steel after recrystallization annealing was studied.The recrystallization annealing temperature was in the range of 1000℃ to 1200℃.The XRD detection results show that the microstructure of sample consists of α phase and γ phase,but has not any new phases generating at recrystallization annealing temperature.After annealing treatment,the size of grains is uniform and equiaxed.At higher annealing temperature,ferrite volume fraction is higher than ferrite volume fraction at lower annealing temperatures.The lower annealing temperature is better than relatively higher annealing temperature of the grain refinement effect,the higher annealing temperatures lead to grain growth.The different recrystallization annealing temperature and the micro-hardness of sample show the complex relationship.
