Abstract In this investigation, a new approach is proposed to calculate in situ true stress and strain in the constituent phases of dual-phase steel during deformation. The model incorporates modified law of mixture and constitutive equations. The model proposes that the deformation of martensite is pseudoelastic, and on little permanent deformation within the martensite allows the locked-in dislocation to release in the ferrite at the interface region of the ferrite and martensite. On application of the model to a set of dual-phase steels with varying microstructural parameters, it is established that the amount of strain partitioning is affected by the strength and amount of the hard phase, as well as grain size, work hardening ability, and yield strength of the softer phase. On the other hand, grain size, carbon content, and fraction and strength of martensite are the main factors controlling the load transfer among the phases.
