Orientation dependence of the martensite transformation in a quenched and partitioned steel subjected to uniaxial tension

The transformation rate of austenite orientations has been investigated by means of electron backscatter diffraction measurements on a pre-defined zone of a quenched and partitioned steel during interrupted tensile tests. The modelled transformation potential, based on the phenomenological theory of martensite crystallography and the mechanical driving force, was found to match the experimental transformation rates in a close correspondence.
