Prediction of Cure‐Induced Wrinkles Aimed at the Manufacturing of Large Wind Turbine Blades

open access: yesPolymer Composites, EarlyView.
The step‐wise progression of the development of cure‐induced wrinkles. Before curing, at room temperature the laminate is resting at the mould face. In the next step, the wrinkle is developing due to thermal gradients. At the end of curing, the composite has cooled down and the undulation is left in, byt the increase in resin stiffness across the ...

Oxidation Performance of NiCoCrAlYTa + 7YSZ Coatings With Ta Addition at Different Temperatures

open access: yesRare Metals, EarlyView.
ABSTRACT This study investigates the morphology and oxidation behavior of thermally grown oxides (TGO) formed at the interface of NiCoCrAlYTa + 7YSZ (7 wt% Y2O3‐stabilized zirconia) coatings deposited by air plasma spray (APS) in air environments at 1050°C, 1100°C, and 1150°C. The enrichment of Ta‐rich oxides beneath the TGO, along with the segregation

Thermodynamics‐Driven Phase‐Field Kinetics Simulation for Experiment‐Validated Design of CoNi‐Based Superalloys

open access: yesRare Metals, EarlyView.
ABSTRACT Thermodynamic prediction‐driven phase‐field kinetic simulation, with experimental verification, is utilized to explore the high‐performance cobalt–nickel based (CoNi‐based) superalloys. The roles of aluminum (Al) in microstructural evolution and precipitation kinetics of ordered L12‐γ′ strengthened Co–Ni–xAl superalloys are revealed. The alloy

Fabrication‐Driven Oxidation Pathways in Y/Hf‐Modified High‐Entropy Alloys: From Elemental Segregation to Oxide Homogeneity

open access: yesRare Metals, EarlyView.
ABSTRACT This study elucidates the oxidation mechanisms governing Y/Hf‐doped AlCoCrFeNiTi high‐entropy alloys (HEAs) and reveals the pivotal role of fabrication processes in dictating high‐temperature oxidation behavior. We demonstrate that casting and spark plasma sintering (SPS) promote Y/Hf segregation, resulting in heterogeneous oxide formation and

Novel Non‐Equimolar High‐Entropy Zirconates With Superior Thermophysical Properties

open access: yesRare Metals, EarlyView.
ABSTRACT Rare‐earth zirconates (RE2Zr2O7) are promising candidates for topcoat materials in thermal barrier coatings (TBCs). However, their practical application in TBCs is limited by poor fracture toughness and low thermal expansion coefficient (TEC).

Thermohydrogen‐Induced α→β Phase Transition and Interfacial Aggregation: A Diffusion Bonding Mechanism for Ti65 Alloy at Low Temperatures

open access: yesRare Metals, EarlyView.
ABSTRACT Diffusion bonding (DB) of near‐α titanium alloys requires high temperatures, which can cause grain coarsening, structural deformations, and degradation of the workpiece's mechanical characteristics. In this study, thermal hydrogen processing (THP) was applied to Ti65, combined with selective magnetron sputtering of a Ti‐Al thin film to promote

Coalescence‐Ripening Mechanism of γ′−Ni3(Al, Ti) During Long‐Term/High‐Temperature Operation of Ni‐Based Superalloy Discs

open access: yesRare Metals, EarlyView.
ABSTRACT The evolution of the γ′−Ni3(Al, Ti) phase in superalloys is governed by a coupled coalescence‐ripening mechanism driven by elemental diffusion. In this study, thermal exposure experiments were performed at 750°C and 800°C for durations ranging from 100 to 20,000 h.
