Microstrain Analysis of Titanium Aluminides [PDF]

Materials Science Forum, 2010
The aeronautic and automotive industries have shown a renewed interest in TiAl based alloys. The main reasons for such an interest are their low density (~3,8g/cm3), a good stiffness and a high strength for temperatures up to 750°C. However, these alloys exhibit, in their polycrystalline form, a poor ductility at room temperature with widely scattered ...

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 ...

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.
