Project Description

The goal of the project is to develop a novel and competitive processing route for manufacturing MoSi2-based composites. Specifically, the project will investigate use of mechanically activated self-propagating high-temperature synthesis (MASHS) followed by compaction. Conventional self-propagating high-temperature synthesis, also called combustion synthesis, promises great advantages such as low energy consumption and low cost, but in case of MoSi2-based materials the reaction rates are not sufficiently high and the products have high porosity and low density. The mechanical activation will improve the reaction kinetics in the subsequent SHS process, while the final compaction will decrease the product porosity. As a result, the problems of SHS will be overcome and its great advantages will be used effectively.

Project Benefits

This project will develop mechanically activated combustion synthesis of MoSi2-based composites that can be used for structural applications in advanced fossil fuel power plants. Improvement to high-temperature advanced materials will promote the development of advanced power plant designs that can operate at higher temperatures and pressures, leading to improvements in efficiency and operational flexibility, and resulting in lower operating costs. As well, this project will promote research and education of Hispanic students in the area of high-performance materials for fossil energy applications.
