| Abstract Scope |
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-enabled investigations of heat affected zone (HAZ) and fusion zone (FZ) process-structure-property relationships in a novel austenitic steel system. Topics covered will include CALuation of PHAse Diagrams (CALPHAD) modeling of solidification behavior and HAZ microstructure evolution under the influence of welding thermal cycles. Experimental validation of simulation results will be reported, and use of validated models to optimize alloy chemistry will be discussed. |
