本研究对316不锈钢渗碳前试样施加静水压应力，以探讨间隙扩散过程与外加应力的关系。比较了碳在过饱和S相中的扩散曲线，讨论了碳在过饱和S相中的扩散系数随浓度的变化规律，以进一步加深对过饱和S相中碳扩散过程的科学认识。实验结果表明，与未施加应力的情况相比，施加压应力可以延缓快速扩散过程。在理论模拟的基础上，讨论了静水压应力对碳在过饱和316奥氏体不锈钢中扩散的影响。
In this study, hydrostatic compressive stresses are applied on the prior-carburized samples of 316 ASS to discover the relationship between interstitial diffusion process and the applied stresses. Carbon diffusion profiles are compared and concentration dependent diffusion coefficients are discussed to further advance scientific understanding of diffusion process in supersaturated S-phase. The experimental results demonstrate that the applied compressive stress can retard the fast diffusion process comparing to the unstressed one. Based on theoretical modelling, the effect of the applied hydrostatic compressive stresses on the diffusion of carbon in carbon supersaturated 316 austenitic stainless steel is discussed.
