Some precipitation reactions in chromium-manganese- nitrogen stainless steels on aging and cold-working

Austenitic stainless steels are subjected to severe
stress and high-temperature conditions in many of
their applications, and also during shaping and
fabrication. These treatments have a profound influ-
ence on their final structure, affecting their phys-
ical, metallurgical and corrosion-resistance proper-
ties. For the prevention of such structural changes,
it is essential to have detailed knowledge of the structural relationship of different phases formed
during mechanical and thermal treatments.
