摘　　要：本文采用单向减薄制样法在透射电镜下观察了氮化08F铜中氮化物的形态及分布。结果表明:在氮化未形变的试样中,亚稳定的氮化物α”—Fe_(16)N_2主要是沿晶体的(100)面析出,同时在奥氏体晶界上也析出片状的氮化物。在形变氮化试样中氯化物主要是在位错缠结区和晶界处析出,而且氮化物的形态也不一样。TEM observation in situ on the single-side thinned specimens was made of nitrides on the steel 08F nitrided and the influence of prior room temperature deformation. The results show that the nitrides precipitate at cleavage plane and at grain boundaries on the specimens nitriddc. The nitrides precipitates at dislocation zooe and grain boundaries on the deformation nitrided specimens in the shape of particle.
