Brief description: This is a response to manufacture IP Turbine casings for the new generation Ultrafan® engine from Astroloy using Net Shape Hot Isostatic Pressing of powder (NSHIP). Astroloy with high γ’ volume fraction have the required high temperature properties but it is unforgeable. Thus, Powder-HIP is the most promising process route for this alloy though this technique presents several challenges such as presence of PPBs in the HIPped microstructure, the high cost of powder and HIP-tooling. HUC, making usage of the background technology will face and overcome these challenges and will take a step further tackling technology gaps alongside the material capability, basic mechanical behaviour and impact in the presence of the exposure with the ultimate goal for this technology to be fully tested in the relevant UltraFan® Demonstrator engine environment. The main objective of HUC is to improve the buy to fly ratio from the typically achieved 9 through the conventional cast and wrought route to less than 3 through NNSHIP being the material developed able to withstand engine relevant conditions with and without exposure guaranteeing its ability to contain.
