CyberAlloys: Computational Design of High-Toughness Steels for Additive Manufacturing

Abstract

Building on previous demonstration of PH Austenitic TRIP Steels optimized for blast and fragment protection, a systems approach to computational materials design is applied to a next generation of such steels optimized for additive manufacturing. Motivated by field applications where densification by Hot Isostatic Pressing (HIP) is not possible, the research seeks to exploit the unique capability of transformation plasticity to offset void softening to achieve a high tolerance for residual porosity.
