Qualification of New, Commercial ODS Alloys for Use in Advanced Fuel Processes

The project will produce a set of data sheets that provide physical, chemical, and mechanical properties for use by equipment manufacturers considering oxide dispersion-strengthened (ODS) steels as a material option for the manufacture of advanced components. Additionally, a technology transfer workshop will be planned to provide an update on the status of ODS alloys including availability, properties, and current capabilities for fabrication of components. The purpose of this task is to determine the capabilities of new, commercially produced ODS alloys for application at temperatures up to 1200 degrees Celsius in environments associated with advanced fossil combustion and conversion processes.

Project Benefits

This project will determine the capabilities of new commercially-produced ODS alloys for application at high-temperatures in environments associated with advanced fossil combustion and conversion processes. Improvement to high-temperature advanced materials will lead to advanced power generation processes with higher efficiencies requiring less fuel input, and producing less carbon dioxide and fewer emissions. Decreased fuel demands will conserve the nation’s fossil fuel resources, place less demand on the fuel delivery infrastructure, and result in lower secondary emissions in the supply chain.
