Recent Progress on Scanning Laser Epitaxy: A New Technique for Growing Single Crystal Superalloys

Abstract

This paper presents recent progress on scanning laser epitaxy, a laser manufacturing technique being developed for achieving single crystal growth in nickel‐based superalloys. Investigations have been performed for creating monolithic deposits on like chemistry single‐crystal nickel superalloy substrates. Progress in the areas of microstructure development and process control will be discussed in the context of repairing high‐value single‐crystal turbine engine components. This work is funded by the Office of Naval Research contract #N00173‐07‐1‐G012.
