Symposium High Temperature Creep Properties of Advanced Structural Materials
Presentation Title Creep and Creep-ratcheting Behaviour of Selective Laser Melted (SLM) Additively Manufactured (AM) Inconel 718

On-Site Speaker (Planned) Milo V. Kral
Abstract Scope The high-temperature performance of Selective Laser Melted (SLM) Additively Manufactured (AM) Inconel 718 is of interest for aerospace applications subject to cyclic thermally-induced stresses. To gain a better understanding of the mechanical performance and material behavior the high-temperature tensile, creep and creep-ratcheting properties at 1000°C have been measured. Creep-ratcheting performance was tested at various stress levels. The microstructural evolution has been investigated at various stages in the creep-ratcheting life to evaluate the accumulated damage. The results of the work will provide insight into the design and service life of components.
