The relations of dislocation density to chemical composition,austempering temperature, tempering treatment and deformation treatment were analysed. Experimental results indicated that the increase in dislocation density was accompanied by the fining of bainite grain. Key words:  bainite ductile iron      dislocation density      X-ray diffraction      Received:  18 June 1996      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1996/V32/I6/573 1WangYuming,LeeShansan,LeeYenchin．JApplCrysiallogr,1982;15:352ZwuiS,ChenGWangY．JMaterSciLett,1985;4:14343TungF,ZwuiS,WangY．JMaterSci,1986;21:32234腾凤恩,崔相旭．物理学报,1989;38:18455滕凤恩,王煜明．金属学报,1989;25:A1586SmithhellsGJ．MetalsReferenceBook．5thed．,London:Butterworths,1976:98 [1] LI Shilei, LI Yang, WANG Youkang, WANG Shengjie, HE Lunhua, SUN Guang'ai, XIAO Tiqiao, WANG Yandong.
