Identification of Constitutive Equation for TRIP Steel and Its Application to Improve Mechanical Properties

摘要

Due to the strain-induced martensitic transformation during plastic deformation, a transformation-induced plasticity (TRIP) steel possesses favorable mechanical properties such as high strength, ductility and toughness. Since its favorable mechani- cal properties are realized under restricted circumstances, the prediction and control of deformation processes are indispensable to determine the expected mechanical properties of TRIP steel.
