RISAssessing the Structural Integrity of Plasma-Sprayed Multilayer Thermal Barrier Coatings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The majority of lifetime models associate the failure of thermal barrier coatings (TBCs) to oxidation of the bond coat (BC). A thickening of the thermally grown oxide (TGO) leads to a conversion of stresses at the undulated ...
Comparison 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 ...
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 ...
High Temperature Fatigue of Welded Joints—Experimental Investigation and Local Analysis of Butt Welded Flat and Cruciform Specimens
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Austenitic stainless steel of type X6CrNiNb18-10 exhibits advantageous mechanical and chemical properties and is a common material for numerous applications in the nuclear power plant and chemical industries. Besides the ...
On the Evaluation and Consideration of Fracture Mechanical Notch Support Within a Creep-Fatigue Lifetime Assessment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Changes within the global energy market and a demand for a more flexible operation of gas- and steam-turbines lead to higher utilization of main components and raise the question how to deal with this challenge. One strategy ...
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. ...
Development and Evaluation of Generic Test Pieces for Creep Property Assessment of Laser Powder Bed Fusion Components
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Metal laser powder bed fusion (PBF-LB/M) allows for high degrees of design freedom and the manufacture of high-temperature Ni-based materials, such as IN738LC. The PBF-LB/M microstructure is dependent on several factors, ...
