During the Paris Air Show, GE Additive announced a significant investment in Arcam electron-beam melting (EBM) technology. An additional 27 EBM systems will be purchased, which brings the total number of units to 62. They will be used to produce titanium-aluminide (TiAl) blades for the low-pressure turbine of the GE9X engine.

Norsk Titanium has successfully printed QuesTek’s custom titanium wire for testing purposes. The microstructure and properties of several heat-treated conditions were evaluated and found to be superior to standard Ti-6Al-4V. While continuing to test, the two companies will work with aerospace manufacturers to demonstrate the benefits of the new alloy/processing.
