Project Description

The goal of this project is to identify and apply breakthrough alloy design concepts and strategies for incorporating improved creep strength, environmental resistance, and weldability into the classes of alloys intended for use as heat exchanger tubes in fossil-fueled power generation systems at higher temperatures than is possible with currently available alloys. Technical objectives are 1.) temperature capabilities that are 50-200 degrees Celsius higher (for both mechanical properties and environmental compatibility) than those of the existing ferritic-martensitic steels, austenitic steels, and Nickel-base alloys: 2.) provide cost-effective new alloys by using less expensive elemental additions as well as inexpensive processing routes.

Project Benefits

A successful outcome of this project will result in higher performance from alloys to be used in fossil-fueled power generation systems. These alloys will be able to operate at higher temperatures and will lead to improvements in efficiency and operational flexibility and result in lower operating costs.
