Abstract

Abstract: Current analysis into the property requirements of materials designed for fragment protection has led to the need for high shear localization resistance to prevent failure from plugging. Transformation induced plasticity (TRIP) is known to significantly delay plastic instability in both tension and shear stress states, thus extending the uniform shear deformation which delays the onset of localization. TRIP-180, a novel computationally designed, fully austenitic TRIP steel, is investigated to explore optimized austenite stability, quantified by the M s σ temperature, under adiabatic shear conditions. It is compared to HSLA-100, a low-alloy martensitic steel, where by a significant improvement in performance is seen.
