Abstract

An optimal proportion of austenitic and martensitic phases is achieved in isometric-phase steels through meticulously designed and elaborately calculated surface nanotechnology. Such isometric-phase steels with nanolamellaed structures and nanograins, exhibit surpassing combinations of strength, hardness and ductility (with yield strength of 1215 MPa, surface hardness of 8.6 GPa, and favorable ductility of 31%). A microstructure-based constitutive model is developed to investigate the deformation mechanism and mechanical performance in isometric-phase steels. We believe the light-weight isometric-phase steels in this work can be regarded as a finer counterpart of dual phase steels for applications in automobile, aircraft and nuclear industry.
