|On-Site Speaker (Planned)
Elevated temperature creep and fatigue experiments were performed on wrought and additively manufactured (AM) Inconel 718. The creep behavior of the AM Inconel was equal or superior than that of the wrought alloy. However, the elevated-temperature fatigue strength of the AM 718 alloy was inferior to the wrought alloy. More noticeably, the high temperature ductility was dramatically lower than the conventional 718. The basis for the dramatic loss in ductility will be discussed.
