RISComparison of Cast, Wrought, and LPBF Processed IN718 Concerning Crack Growth Threshold and Fatigue Crack Growth Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study focuses on the influence of microstructure and ductility on the short crack behavior and the fatigue crack growth (FCG) threshold. For this, an additively manufactured batch of the nickel-based alloy IN718, made ...
Deformation and Damage Behavior of a 1Cr-Cast Steel Under Multiaxial Loading at Elevated Temperatures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rising demands on material performance at high temperature in components under complex loading such as steam- and gas turbine housings require an increase in versatility and precision of component life modeling approaches. ...
Toward a Better Understanding of Crack Growth in Nickel-Cast Alloys Under Creep-Fatigue and Thermo-Mechanical Fatigue Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To ensure the feasibility of gas turbines, despite rising commodity prices and emission restrictions, an enhancement of both their efficiency and flexibility is necessary. The consequential higher loading of components at ...
