Abstract
A new technique has been developed in which the surface of an alloy is rapidly melted and resolidified with a high-energy laser or electron beam, resulting in a uniform and stable microstructure. The process was developed to increase the service life of the space Shuttle main combustion chamber (MCC) liner, which was found to be degraded because of nonuniform microstructure, grain growth, grain boundary precipitation of intermetallic phases, and high-temperature deformation that cause grain boundary coarsening and sliding.
