| Abstract: | Diffusion in a typical joint of a stainless steel and a low-alloy steel has been simulated by means of the DICTRA software in a temperature range between 600 °C and 1200 °C. Calculated carbon concentration profiles are shown. A comparison with experimental data is made for a simulation at 650 °C. The simulations also predict how the amount of the various phases varies with the distance from the joint. The amount of carbon transported across the joint is evaluated as a function of temperature. |
