Abstract:
Titanium alloys are well known for their high strength to weight ratio. However, its use is restricted in many sectors simply due to its high cost when processed through the conventional route. Powder metallurgy has been proven as an alternative way to reduce the cost of near-net shape titanium components. The cost of powder is related to its source, but technologies like additive manufacturing (AM) produce large quantities of surplus powder that can be reused with alternative technologies. Alternatively, the option to use titanium machining swarf as a feedstock material is also explored to further reduce the price of titanium components.In this work, Ti-6Al-4V swarf and surplus AM powder has been consolidated using field-assisted sintering technology (FAST) and hot isostatic pressing (HIP). The consolidation, microstructure and hardness has been assessed to explore and compare the potential of these technologies in the production of low-cost titanium near-net shape parts.
