Abstract

Discussed is the recent progress on scanning laser epitaxy, a laser manufacturing technique under development for achieving single crystal growth of nickel-based superalloys. Experimental investigations have been performed on the single-crystal capable nickel alloy CMSX-4. Additionally, mathematical models have been coupled with analytical information obtained from experiments to understand the scanning laser epitaxy process and the requirements to achieve monolithic deposits on like chemistry single-crystal nickel superalloy substrates. Presentation of microstructure development and need of process control in the context of the laser generated melt pool will be discussed from the view-point of repairing high-value single-crystal turbine engine components. This work is funded by the Naval Research contract #M00173-07-1-G012.
