The next generation of aircraft engines aims for continuous improvement of performance and efficiency, while reducing emissions.
However, the higher temperatures involved severely stress turbines’ constitutive materials.
Current casing materials are designed to work at 650°C. Superalloys like Inconel 718 or Waspaloy® are typically used. Different aircraft engine producers have different strategies to develop more efficient turbines with materials and manufacturing routes designed to provide casings which can operate at 700 to 800°C. HIP technology is one of these solutions.
