Manufacturing of large size nickel-based single crystal turbine guide vanes by grain continuator technology

Large size nickel-based single crystal twin turbine guide vanes（TGVs）were prepared by grain continuator（GC）technology. Directional solidification was performed in a high-rate-solidification（HRS）Bridgman vacuum furnace. Then, the macro-etching test was carried out to reveal the single crystal integra...
