Arcast Inc., Oxford, Maine, USA, reports that it has successfully produced a titanium superalloy powder with an as-atomised D50 of 20 µm, with narrow size distribution and with little-to-no oxygen pick-up. The alloy was produced using Arcast’s proprietary atomising process.
Arcast’s process consumes relatively little gas and has zero risk of ceramic/oxide contamination, the company states, making it possible to process metal alloys which other methods cannot. Powders produced by this method can be used in Additive Manufacturing, Metal Injection Moulding and other Powder Metallurgy processes. The production of powder by this process also does not require specialist feedstock.
Arcast stated that the new alloy is now being produced in significant quantities. With its growing capacity to produce as-atomised, advanced titanium alloys (along with other challenging metal alloys) from a range of low-cost feedstock, Arcast states that it can offer a complete solution for Additive Manufacturing, Metal Injection Moulding and other Powder Metallurgy markets.
