本文对钢在氮基保护气氛奥氏体化过程中氢的扩散问题进行了研究。结果表明:在保护奥氏体化过程中钢样中氢的化学势比气氛中高而导致钢中的氢向保护气氛中扩散。
In this paper, the diffusion of hydrogen in the process of austenitizing steel under nitrogen-based protective atmosphere was studied. The results show that the chemical potential of hydrogen in the steel sample during the austenitizing process is higher than that in the atmosphere, causing the hydrogen in the steel to diffuse into the protective atmosphere.
