Although the thermochemistry of these systems is reasonably well-established, it is clear that the kinetics of the reactions involved are rather complex and hence not as well defined. The role of precipitated nitrides is also considered, since this feature is an integral part of the use of filters as well as being a core facet of the nitride removal reaction in several of the processes surveyed. We also review the present position in respect of the production of high-nitrogen alloys, including the role of systems relying on the presence of N + ions to establish concentrations greater than those predicted by Sieverts' Law. We conclude that the basic information needed to establish a rational production route for any given alloy affected by nitrogen content is available, but that a very careful consideration of all the factors involved is required before defining such a route.","claims":[{"public_id":"cl_b7a88a6837279c6c71d2ef7bbad1e247","status":"active","text":"Basic information needed to establish a rational
