AbstractA new ultra-high strength maraging stainless steel with composition of 13Cr-13Co-4.5Ni-3.5Mo-0.5Ti (at.%) has been developed. It was demonstrated that the ultimate tensile strength of the steel could reach 1.9 GPa with reasonable ductility. This breakthrough was achieved by a combined strengthening of three different species of precipitates. The evolution of precipitates with respect of size, morphology and chemical composition during aging at 500 degrees C was characterized using atom probe tomography (APT) and transmission electron microscopy (TEM). The precipitates were identified to be eta-phase Ni-3(Ti,AI) phase, Mo-rich R' phase and Cr-rich alpha' phase, developing out of the precursor clusters, Ni-Ti-Al-rich cluster, Mo-rich cluster and Cr-rich cluster, separately. The segregation of Mo and Cr atoms at the precipitate/matrix interfaces was detected and is considered to impede the coarsening of eta-phase. Based on the characterizations, the precipitation process of these phases and their effect on mechanical properties were analyzed. (C) 2015 Elsevier Ltd. All rights reserved.
