Identification of Retained Austenite, Ferrite, Bainite and Martensite in the Microstructure of TRIP Steel
Transformation induced plasticity (TRIP) steels have a vast application in automotive industry because of theirhigh strength, high ductility and hence excellent energy absorption capacity. These characteristics of TRIPsteels are due to the existence of retained austenite in their microstructures in the ambient temperature, whichtransforms to the martensite phase during deforma...
متن کاملSimulation of an Austenite-Twinned-Martensite Interface
Developing numerical methods for predicting microstructure in materials is a large and important research area. Two examples of material microstructures are Austenite and Martensite. Austenite is a microscopic phase with simple crystallographic structure while Martensite is one with a more complex structure. One important task in materials science is the development of numerical procedures whic...
متن کاملTransformation potential predictions for the stress-induced austenite to martensite transformation in steel
The stress-induced transformation behavior of retained austenite is considered in this work. With the development of transformationinduced plasticity (TRIP) steels this deformation mode is of growing importance. Twinned martensite structures were calculated using the crystallographic theory of martensite. An available work criterion was used to predict the transformation potentials for 16 diffe...
متن کاملAn analysis of non-classical austenite-martensite interfaces in CuAlNi
Ball & Carstensen [2, 3], theoretically investigated the possibility of the occurrence of non-classical austenitemartensite interfaces and studied the cubic-to-tetragonal case extensively. Here we aim to present an analysis of such interfaces recently observed by Seiner et al. [12] in CuAlNi single crystals, undergoing a cubic-toorthorhombic transition. We show that they can be described by the...
متن کاملStabilization of Austenite Associated with Prior Formation of Martensite
The stabilization of retained austenite was studied via a two-step cooling procedure. Alloys with M , temperatures below 0 OC were used. It was found that the martensitic transformation starting temperature, M,, was lowered to M,' during the second step of cooling. With increasing the amount of previously formed martensite, the difference in the transformation starting temperatures, AM, (= M,M,...
