Near-net-shaping hot isostatic pressing (NNS-HIP) method was used for once-forming complex monolithic Ti6Al4V alloy bladed disks manufacturing. The complex monolithic bladed disks were formed successfully in a near-net-shape manner using the proposed HIP mold scheme in this study. The results showed that there were fine and homogeneous strip α+β phases and no obvious pores or cracks were detected. A "layered" phenomenon was observed in as-built part microstructure. The tensile strength value of specimens from the NNS-HIP bladed disks in the same furnace reached 900MPa, which was higher than the values of parts manufactured using casting and forging processes. The fracture morphology analysis showed that the sample had a ductile fracture. This study provides a reference to the NNS-HIP for the bladed disk parts manufacturing.

Ti-5Al-2.5Sn ELI alloy is a typical α titanium, which is widely used at cryogenic temperatures. Hot isostatic pressing (HIPing) is a common technology to fabricate powder metallurgy (P/M) titanium alloys and components. Porosity control is very crucial for P/M alloys during application, and porosity will deteriorate mechanical properties of P/M alloys. In this study, porosity caused by HIPing process has been investigated. Effects of porosity on metallurgy quality of P/M Ti-5Al-2.5Sn ELI alloy have been accessed. The results showed that when porosity levels was less than 0.6%, no significant difference was found comparing with full dense P/M Ti-5Al-2.5Sn ELI alloy. Near-net-shape forming processes of P/M titanium alloy parts ware studied. By using metal capsules and metal internal tooling, near-net-shaping of P/M parts with complex shapes was demonstrated.
