The thesis reports work aimed at assessing diffusion bonding during Hot Isostatic Pressing (HIPping), with the long term aim of developing re-usable tooling for the manufacture of near net shape aero-engine components from Ti-6Al-4V (Ti-6-4). Microstructural analysis and mechanical property assessment have been carried out on several different types of sample in order to define the potential of this process-route when using different starting materials and different HIP procedures. This research work is split into three sections; the first section consists of optimising the process parameters for solid-state or solid-to-powder HIP-DB of Ti-6-4 to produce monolithic or integrated engineering components, the second section consists of developing a two-stage approach, which would be required if reusable tooling is to be developed for near net shape HIPping for solid-to-powder HIP-DB of Ti-6-4. Finally the third section consists of work to develop a fixed tool process using high temperature-resistant reusable tooling and solid or powder Ti-6-4 to produce near net shape (NNS) components using mild steel as a sacrificial canister or encapsulation material.
