Since the development of gas turbine engines, the demand for decreased costs and increased performance has required components that can withstand higher temperatures and longer service lives. 

Modern turbine components, such as nozzle guide vanes (NGVs), which are responsible for directing and harnessing the violently expanding gases from fuel combustion, are made of advanced nickel-based superalloys cast using solidification techniques, like single crystallization, and inc..
