TRIP steel TRIP steel is a high-strength steel typically used in the automotive industry. TRIP stands for "Transformation induced plasticity." It is known for its outstanding combination of Strength and Ductility. ==Microstructure== TRIP steel has a microstructure consisting of retained Austenite in a ferrite matrix. Apart from Retained Austenite it also contains hard phases like Bainite and Martensite.〔http://www.worldautosteel.org/steel-basics/steel-types/transformation-induced-plasticity-trip-steel/〕 The higher silicon and carbon content of TRIP steels results in significant volume fractions of retained austenite in the final microstructure. TRIP steels use higher quantities of carbon than Dual Phase steels to obtain sufficient carbon content for stabilizing the retained austenite phase to below ambient temperature. Higher contents of silicon and/or aluminium accelerate the ferrite/bainite formation. They are also added to avoid formation of carbide in the bainite region.
