On the Stability of Microstructure for GeneralMartensitic
نویسنده
چکیده
We describe a general theory for the stability of the laminated mi-crostructure for martensitic crystals. Our theory has been applied to the orthorhom-bic to monoclinic transformation, the cubic to tetragonal transformation, the tetrag-onal to monoclinic transformation, and the cubic to orthorhombic transformation.

Microstructural evolutions during annealing of cold rolled AISI 304L and AISI 316L stainless steels were studied. Cold rolled AISI 304L alloy was fully martensitic but cold rolled AISI 316L alloy was partially martensitic due to the higher stability of the austenite phase in the latter. During continuous heating to elevated temperatures, the complete reversion of strain-induced martensite at 75...
