Mechanical and wear behaviour of AZ91D magnesium matrix hybrid composite reinforced with boron carbide and graphite

The utilization of particulate reinforced aluminium hybrid metal matrix composites is being increased in automotive applications due to its distinct properties. In the present study, an endeavour has been made to synthesize Al7075 aluminium alloy with reinforcement of B4C and MoS2 as lubricant under various weight percentages of 4%, 8% and 12% using stir casting process. The compressive strength, tensile strength, hardness, micro structural analysis and tribological behavior of the synthesized hybrid composites have been analyzed and investigated. From the experimental investigation, it has been observed that the reinforcement particles are uniformly distributed in the matrix alloy as fine dendrites in alumnium solid solutions. The tensile strength, compressive strength, and hardness of the reinforced composites could be increased by adding the reinforcement compared to monolithic alloy. The significant improvement of wear resistance and coefficient of friction of aluminium hybrid composites has been achieved owing to inclusion of solid lubricant (MoS2) along with hard ceramic reinforcement particles (B4C) in the matrix alloy.

Lattice structures, which are also known as architected cellular structures, have been applied in various industrial sectors, owing to their fascinated performances, such as low elastic modulus, high stiffness-to-weight ratio, low thermal expansion coefficient, and large specific surface area. The lattice structures fabricated by conventional manufacturing technologies always involve complicated process control, additional assembly steps, or other uncontrollable factors. Furthermore, limited types of unit cells can be used to construct lattice structures when using conventional processes. Fortunately, additive manufacturing technology, based on a layer-by-layer process from computer-aided design models, demonstrates the unique capability and flexibility and provides an ideal platform in manufacturing complex components like lattice structures, resulting in an effective reduction in the processing time to actual application and minimum of material waste. Therefore, additive manufacturing relieves the constraint of structure design and provides accurate fabrication for lattice structures with good quality. This work systematically presents an overview of conventional manufacturing methods and novel additive manufacturing technologies for metallic lattice structures. Afterward, the design, optimization, a variety of properties, and applications of metallic lattice structures produced by additive manufacturing are elaborated. By summarizing state-of-the-art progress of the additively manufactured metallic lattice structures, limitations and future perspectives are also discussed.
