Quantitative measurement of strain partitioning and slip systems in a dual-phase steel

The strain partitioning of ferrite and martensite in a dual-phase steel after tensile deformation has been investigated. There was more strain accommodated in the ferrite phase due to its being the softer of the two phases. The orientation of the ferrite was not found to contribute to strain localization, and it was concluded that the morphology of the microstructure was the most dominant factor affecting strain localization.
