Abstract

This chapter is on techniques that can be used to improve the properties of stainless steels. Some of these techniques improve surface properties, while some of them enhance the properties throughout the bulk of the material. Many of the techniques improve properties through grain refinement, whereas some rely on a phase transformation. Some of the techniques are specifically devised for a particular type of stainless steel (the technique that utilises reverse transformation of martensite is mainly for the austenitic type) or for steels in the liquid state.


Keywords: Surface modification, laser surface modification, grain refinement, carburisation, colossal carbon saturation, Kolstering, S-phase, nitridation, heavy plastic deformation, martensite, reversion transformation, intercritical annealing.
