| Abstract Scope |
This presentation elucidates the ductility loss phenomenon in additively manufactured (AM) Haynes 214 alloy at elevated temperatures, which significantly limits its application across an extended temperature range. We establish the evolution of mechanical properties across temperatures ranging from ambient to 1000C, elucidating the specific temperature threshold at which ductility loss occurs and its correlation with mechanical strength. The combined influence of size effect and thermomechanical response is leveraged to present a discussion on the microscopic deformation mechanisms across different length scales that govern the characteristics of macroscopic response, including the Portevin-Le Châtelier (PLC) effect and ductility loss. |
