Abstract

Analysis of the dynamic evolution of multilevel structure during martensitic transformations provides kinetics-based constitutive relations for transformation plasticity. Application in numerical modeling of ductile fracture by microvoid-softening-induced shear localization, in conjunction with metallographic study of crack-tip processes, identifies transformation toughening mechanisms operating on three structural length scales. Dispersed-phase transformation toughening in ultrahigh-strength martensitic steels demonstrates record levels of fracture toughness.
