Effect of Porosity on Mechanical Properties of Ti-5Al-2.5Sn ELI Alloy from Atomized Powder

Abstract:

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.
