Project Description

This project will develop high resolution methods for modeling the three dimensional mechanical response of metallic alloys when exposed to high temperatures. The methodology will include three (3) dimensional microstructure generation from microscopy data, and an image-based method for high resolution simulation of mechanical response. The technical focus will be on simulating plastic deformation and damage accumulation of polycrystalline materials at the grain scale.

Project Benefits

This project will develop high resolution modeling of materials for high temperature service. The expected results are development of new software and computational tools that will allow material developers and engineers to rapidly evaluate how variations in the designed microstructure of metal alloys will impact the mechanical behavior of materials at high temperatures. By reducing the time required for material analysis and selection, faster development of cleaner and more efficient fossil energy-based power generation technologies will be achieved. Ultimately, improvements to high-temperature advanced-materials will promote the development of advanced power plant designs that can operate at higher temperatures and pressures, leading to higher efficiency, operational flexibility, and lower operating costs.
