Qualification and Certification of Nickel based C1023 Super Alloys for Aero-Engine Applications

Abstract

The Nickel-based super alloys are favoured for manufacturing turbine blades and vanes because these alloys can withstand high temperatures with high-stress levels. The microstructure of C1023 in as-cast condition exhibits a dendritic structure and few secondary particles. In this study, the room temperature tensile (1063±7 MPa) and high temperature (800 °C and 850 °C) stress rupture is carried out the life obtained is 92 hrs and 74 hrs respectively of cast alloy C1023 super alloy. The main objective of certification societies like CEMILAC is to qualify and certify metal parts through the development of guidelines, standards, and specifications that address technical and operational challenges in the manufacturing process. In tandem with the advancement of technology and the transformation of the industry, the qualification and certification methodology will evolve.
