TLDR
In this paper, a theoretical approach is proposed to take into the account nucleation, growth and coarsening of nitrides in alloys featuring heterogeneous nitrogen content, which is based on physical considerations and accounts for both bulk nitrogen diffusion, which results from the nitriding process and Nitrides precipitation kinetics.About:

Investigation of a Ferrite/Silicon Nitride Composite Concept Aimed at Automotive Applications
TL;DR: In this article, the behavior of a Fe-15µwt% Si thin sheet upon plasma-assisted nitriding at 570°C was investigated and it was shown that a very fine and intense precipitation of amorphous silicon nitride occurs as nitrogen diffuses into the sheet.
