Carbon Diffusion In Steel. Diffusion only happens through a small thickness of a piece of steel so only the surface is hardened while the core maintains its original mechanical properties. Heat transfer engineering and design.

Diffusion only happens through a small thickness of a piece of steel so only the surface is hardened while the core maintains its original mechanical properties. Diffusion of carbon in austenite for iron carbon alloys as well as for steels alloyed with a variety of ele ments. The figure gives the migration energy e m and pre exponential factor d 0 as a function of carbon concentration for carbon diffusion in austenite.
Heat treatment is a process to alter the metallurgical and mechanical properties for specific purposes.
The proposed empirical model provides a pragmatic engineering approach to this important diffu sion process. Diffusion hardening is a process used in manufacturing that increases the hardness of steels. Before discussing carburizing parameters carbon diffusion in the steel should be analyzed. The model is shown to better match the carbon diffusion profiles of several carburized steel.
