Analysis on migration phenomena of carbon in welding transition region between stainless steel and heat-resistant steel
摘要
Abstract
In order to carry out the quantitative analysis on the migration process of carbon during the welding of dissimilar steels such as both stainless steel and heat-resistant steel and aiming at the carbon migration phenomena occurred in the fusion area,the actual concentration of carbon was firstly converted into the equivalent concentration according to its chemical potential gradient,and then the calculation for the diffusion process was performed with Fick's law.According to the calculated results,the theoretical formula for the diffusion of carbon was derived,and the theoretical diffusion curves were drawn.The component analysis along the direction perpendicular to the fusion line was performed with scanning electron microscope,and the actual diffusion curves of carbon were drawn.The results show that the theoretical and measured curves are basically the same.With the present method,the migration trend of carbon can be derived more accurately.It means that the proposed method can provide the theoretical basis for investigating the diffusion of carbon in dissimilar steels.关键词
