Titanium alloy components are highly desirable in many applications due to their well-known combination of excellent properties. Therefore, cost-effective production is of considerable interest. Research was undertaken to consolidate titanium alloy powder from the Metalysis process using the FAST-forge technique to produce a demonstrator landing gear component in just three steps; giving scope for considerable cost reductions. The first step is electrochemical reduction of titanium oxide into titanium alloy powder via the Metalysis process. Steps two and three produce a shaped preform billet via field assisted sintering technology (FAST) that is finished to near net shape via a forging operation - collectively termed FAST-forge. Initial results indicate the mechanical properties of an alloy derived directly from synthetic rutile (beach sand) and processed through FAST-forge compare favourably with conventionally produced wrought Ti-6Al-4V. Combining lower-cost alternative feedstocks with FAST-forge offers the potential to produce a step-change in the economics of titanium.
