Nanocalorimetry of Nanoscaled Ni/Al Multilayer Films: On the Methodology to Determine Reaction Kinetics for Highly Reactive Films

Advanced Engineering Materials, Volume 27, Issue 3, February 2025.
Free‐standing Ni/Al multilayer thin films are investigated with a novel commercial nanocalorimeter and a conventional calorimeter. The Kissinger analysis shows a monotonic Arrhenius behavior over the entire five orders of magnitude of heating rates for all thermal events.

Dual coating layers to enhance oxidation resistance for refractory high-entropy alloys

Results in Materials
Refractory high-entropy alloys (RHEAs) possess excellent high-temperature mechanical properties, making them have the promising potential for applications at temperatures higher than Ni-base superalloys.

RuAl Thin‐Film Deposition by DC Magnetron Sputtering

Advanced Engineering Materials, Volume 27, Issue 3, February 2025.
The synthesis and influence of deposition parameters on the corresponding microstructure of single‐phase RuAl in B2 structure is examined via transmission electron microscopy analysis and X‐ray diffraction with additional pole figure measurements. These are correlated to mechanical properties of the magnetron‐sputtered thin films.

Multiperspective Structural Integrity Investigations on the Rotor Blade of Axial Flow Compressor Under Various Rotodynamic Loading Conditions Using Enhanced Computational Analyses

International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.
Small gas turbine (SGT) engines power the latest generation of unmanned aerial vehicles (UAVs). This study investigates the axial flow–natured rotor blades of an SGT compressor. Rotor structures in axial flow compressors have failed due to complex stress scenarios.

Multiobjective Optimization of Fiber Laser Trepan Drilling for Stainless Steel Using Taguchi–Grey Relational Analysis

Journal of Engineering, Volume 2025, Issue 1, 2025.
The present work focuses on optimizing spatter size, taper angle, and circularity simultaneously during fiber laser trepan drilling of stainless steel thin sheet using Taguchi–grey relational analysis (GRA). The controllable process factors such as trepanning speed, average laser power, and pulse frequency with five levels are applied to conduct the ...

Iron Aluminide Composites [PDF]

MRS Proceedings, 1998
ABSTRACTIron aluminides with the B2 structure are highly oxidation and corrosion resistant. They arethermodynamically compatible with a wide range of ceramics such as TiC, WC, TiB2, and ZrB2. Inaddition, liquid iron aluminides wet these ceramics very well. Therefore, FeAI/ceramic compositesmay be produced by techniques such as liquid phase sintering of

Development and characterization of in‐situ nickel aluminide reinforced Al‐Si matrix composites by stir casting

Engineering Reports, Volume 6, Issue 12, December 2024.
The graphical abstract demonstrates that adding 9 wt% nickel to an Al‐Si matrix composite increases hardness by 25.93%, tensile strength by 40.3%, and density by 6.01%, but decreases impact strength by 50% compared to the A413 alloy. It includes SEM images, a stir casting schematic, and data on tensile and impact behavior.
