Project Description

The objectives of the proposed research are two-fold: (a) develop a methodology for microstructural optimization of alloys - genetic algorithm approach for alloy microstructural optimization using theoretical models based on fundamental micro-mechanisms, and (b) develop a new computationally designed Ni-Cr alloy for coal-fired power plant applications. The broader outcome of these objectives will be the creation of an integrated approach for ‘materials by microstructural design’.

Project Benefits

This project will develop a methodology for microstructural optimization of alloys for high temperature structural materials. The development of nanostructured alloys will provide significant opportunities to develop materials with exceptional strength and promote the development of advanced power plant designs that can operate at higher temperatures and pressures, leading to improvements in efficiency, operational flexibility, and resulting in lower operating costs.
