Abstract

Ti60 alloy with excellent high-temperature strength (820 MPa at 600 °C) was fabricated via Directed Energy Deposition. However, silicide and Ti₃Al precipitation are suppressed due to ultrahigh cooling rate, leading to its creep life being less than half that of forgings. Compositions of conventional titanium alloys need re-engineered for additive manufacturing.
