摘要

The ongoing advancements in materials science have fueled extensive investigations into the field of metal-embedded composites with improved engineering and thermoelectric effects, specifically aluminum-embedded composites. This research deals with the fabrication of AA2124 aluminum alloy composites fortified with varying contents (5 to 20%) of aluminum-titanium-vanadium-niobium-molybdenum (AlTiVNbMo) as high-entropy alloy (HEA) compounds. The principal outcomes indicate that HEA reinforcement enhances the compactness and mechanical strength of the aluminum alloy materials. There exists an intricate connection between the HEA constituents and the resulting mechanical properties. The composition with 20% AlTiVNbMo yielded the optimum performance, with a density of 2.7 g/cm3, ultimate tensile strength of 165 MPa, and 18% elongation. Excellent thermal conductivity was observed at this composition, although it was accompanied by decreased electrical conductivity due to increased phonon scattering. The hardness measurements, conducted using Rockwell C and Vickers hardness methods, revealed a significant improvement in the material’s resistance to plastic deformation. Thus, the present research provides a strategy to enhance the properties of composites for significant applications across various fields.
