摘要

Abstract

novel type of austenite–martensite dual-phase laminate steel with a yield strength of 2.2 GPa

ultimate tensile strength of 2.5 GPa

uniform elongation of 9.4% and total elongation of 12% was produced. Such unexpectable mechanical properties were mainly due to the synergistic strengthening of nanolaminate microstructure

high densities of dislocations and nanoprecipitates. The high uniform elongation at very high stress could be attributed to the strongly enhanced work hardening rate

mainly enabled by transformation-induced plasticity (TRIP) of the austenite reverted by annealing

as well as the cooperative deformation and stress/strain partitioning between the austenite–martensite stacked nanolaminate.
