The results reveal that in the white and transition areas, which are the subdivisions of the layer, nitrides preciptate greatly in the form of needle and at grain boundaries in the form of network. These cause about 100 μm microcracks in the white area. The extraordinary microstructure of the layer indicates that Al-containing alloy steels are not suited for sulfo-nitro-carburizing treatment in salt bath.Corresponaent: GONG Xiumin, (professor, Wuhan Automotive Polytechnic University, Wuhan 430070) Key words:  sulfo-nitro-carburizing in salt bath      Al-containing alloy steel      nitride      Received:  18 August 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/I8/829 1AB著,田至敏译．钢与铸铁的硫碳氮共渗．北京:机械工业出版社,1982:712ThelningK-E．SteelandItsHeatTreatment．London:Butterworths,1975:3773著,郭铮匀译,钢的氮化,北京:国防工业出版社,1979:104胡以正．材料保护,1985;D(5):525宫秀敏．机械工程材料,1993;(10):166宫秀敏．热加工工艺,1994;(3):11" [1] Yinhui ZHANG,Mei LI,Larry A GODLEWSKI,Jacob W ZINDEL,Qiang FENG.
