Design Optimization of 10Ni Naval Steels

Abstract

APPROVED FOR PUBLIC RELEASE Under a Navy-coordinated collaboration to deliver a new class of weldable 10Ni steels combining high-str,ength and toughness enabling a broad range of applications in naval structures, proposed MIT research combines genomic computational, materials design with advanced microstructural characterization for ICME-based acceleration of materials development and qualificat,ion. Martensite/Austenite microstructures achieved by 2-step tempering will combine efficient carbide secondary hardening with dispe,rsed-phase transformation toughening, with alloy composition constrained for high weldability. System-specific quantitative applicat,ion of mechanistic knowledge is enabled by parametric design grounded in genomic CALPHAD databases of fundamental thermodynamic and, kinetic parameters.
