ZHAI Qijie HU Hanqi University of Science and Technology Beijing %A China associate professor %A Faculty of Foundry %A University of Science and Technology Beijing %A Beijing %A China %J 金属学报(英文版) %D 1993 %I %X Effect of nitrogen on matrix structure of 3 different varieties of gray cast iron,i.e., sub-eutectic Fe-C-Si,near-eutectic Fe-C-Si and Fe-C-Si-Mn,has been investigated. The eutectie colony structure of gray cast iron may be refined,the pearlite content increased and the micro-hardness of pearlite and ferrite raised with an addition of nitrogen.The influ- ence of nitrogen on the transformation temperature of the equilibrium and non-equilibrium phases,as well as,the solution of nitrogen in ferrite and cementite seem to be the major rea- sons to strengthening the matrix structure of gray cast iron. %K nitrogen %K gray cast iron %K matrix structure %K microhardness %K solid solution
