Grain Boundary Modification in Aluminum Hybrid Nanocomposites (Al6061-TiC) Using Borophene Material

Purpose

This study aims to explore the crystallographic properties and microstructural development of Al6061-TiC-borophene hybrid composite materials and their impact on mechanical and tribological properties. Crystal engineering in aluminum-based composite materials is a crucial step toward enhancing their mechanical properties, hardness, and wear resistance. The addition of titanium carbide particles as a reinforcing agent in the Al6061-TiC-borophene composite material provides a hybrid strengthening mechanism. Crystal engineering in Al6061-TiC-borophene composite materials aims to explore their crystal structure formation and the interaction between the phases, which enhance the structural and functional properties.

Approach

The crystallographic characteristics of Al6061-TiC-borophene hybrid composite materials are studied using microstructural characterization and phase characterization methods. In the composite synthesis process, heterogeneous nucleation is carried out using TiC particles, which refine the aluminum crystal structure. Borophene helps in nanoscale reinforcement and interfacial bonding. X-ray diffraction, scanning electron microscopy, and electron backscatter diffraction methods are used to study the crystallographic characteristics.

Findings

The reinforcement of TiC and borophene contributes to better crystallographic stability and enhanced mechanical properties in Al6061. The development of refined equiaxed grains and stable interfacial compounds improves hardness and wear properties. In addition, it improves load-carrying properties. The reinforcement of TiC improves stiffness and acts as barriers to dislocations. Borophene contributes to strengthening and stress transfer. The crystal structure refinement contributes to reducing microstructural defects and improving uniformity in the composite matrix. This improves microstructural properties compared to conventional aluminum alloys.

Practical Implication

The optimized crystal structure of Al6061-TiC-borophene composites provides strong potential for use in lightweight structural components used in the aerospace, automotive, and advanced manufacturing industries. The enhanced wear resistance, strength-to-weight ratio, and thermal stability of the composites make them appropriate for the development of advanced engineering systems.
