摘　　要：用透射电镜电子衍射法研究了T12钢渗钒层的相结构。结果表明,碳化物主要为六角点阵的V_6C_5,其点阵常数a=0.509nm,c=1.440nm。碳化物层中存在少量四方点阵的σ-FeV.V_6C_5与VC晶面和晶向的取向关系为:(100)//(110)_(vc)(S为V_6C_5超点阵的代号),(001)//(111)_(vc),[210].//[110]_(ve),[001]//[111]_(vc)。The structure of vanadized zone in tool steel T12 has been investigated by electron diffraction of TEM. The results show that the lattice parameters a and b of V6C5 carbides are 0. 509 nm and 1. 1440 nm, respectively. A small amount of a- FeV with tetragonal lattice exists in the alloy, the parameters of which are 0. 893 nm and 0. 481 nm, respeotively. The orientation relationships are (110)// (110)Vc, (001)// (111)VC,[210],//[110]VC,[001]//[111]VC.
