During fracturing, the microstructural chan-ge was taken place in the crack tip zone, The cracks will propagate on the second-ary pearlite structure. It is believed that the fracture toughness of 16MnR steel isdependent on the diffusion of carbon atoms and the formability of secondary pearl-ite structure. Key words:  16MnR steel      prestrain      diffusion      fracture toughness      secondary pearlite      Received:  18 January 1991      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/Y1991/V27/I1/49 1 赵志业.金属的塑性变形与轧制理论,北京:冶金工业出版社,1980 2 曹乃光.金属的塑性加工原理,北京;冶金工业出版社,1983 3 肖纪美.合金相与相变,北京:冶金工业出版社,1987 4 Amouzouvi K F, Bassim M N.
