Integrated Computational Materials Engineering (ICME) principles and methods have enabled accelerated development and transition of new materials in many industries. In order to establish and evaluate an ICME framework relevant to the design of naval materials, engineers at Naval Surface Warfare Center, Carderock Division and Naval Research Laboratory are engaged in a program to concurrently develop a base material and welding filler metal system using computational, statistical, and experimental methods. This presentation reports work to date on ICME investigations of heat affected zone (HAZ) and fusion zone (FZ) process-structure-property relationships in a novel austenitic steel alloy system. Topics covered will include modeling of HAZ and FZ microstructure evolution under the influence of multiple welding thermal cycles and optimization of filler metal composition for weldability and mechanical behavior using thermodynamic simulation, finite element analysis (FEA), and design of experiments (DOE) methods.
