Abstract

A predictive model for the carbon concentration profile in vacuum carburized steels with acetylene was proposed. The model involves the process and boundary conditions based on the characteristic of vacuum carburizing with acetylene and carbon diffusivity with an alloying element effect. In order to verify the predictive model, the carbon concentration profile of a cylindrical SCM415 steel specimen vacuum carburized with acetylene was calculated using the finite element method. The carbon concentration profile calculated with the alloying element effect, the carbon diffusivity in the Fe-C binary system proposed by Tibbetts, and multiple time steps of carburizing and diffusion exhibited good agreement with the measured carbon profile.
