“…The reinforcement mechanism of submicron TiB 2 particles in the molten Al 7075 matrix by experimental and theoretical methods was analyzed, the results of the study showed that with increasing TiB 2 content, the grain size increased by about 58% resulting in a significant increase in mechanical properties [1]. TiB 2 composite reinforced Al 7075 matrix by laser melting deposition method was produced, and concluded that grain size was greatly reduced and the mechanical strength was also improved [2].…”

The rapid development of Aluminium composites with advanced hybrid materials is increasing due to increasing demand. This composite material is used in many applications in the aerospace and automotive industries due to its lightweight, good corrosion resistance and high thermal resistance. To meet this demand, this study focused on the development of Al-7075 alloy reinforcements containing TiB2 and graphene, using Aluminium-7075 as the base material, mixed with TiB2 and graphene to measure and improve mechanical and tribological properties by using stir casting technique, with the proposed graphene content of 1%, 2% and 3% and TiB2 content varying between 1 to 15% of its overall weight. With the addition of TiB2 and graphene properties such as hardness, tensile strength, impact strength and tribological behaviour are improved. The 12% reinforcement combination (i.e. 10% TiB2 and 2% Gr) exhibit better tensile strength, hardness and wear resistance. Microstructure and phase characterization of the composite material are analyzed using scanning electron microscopy (SEM) and x-ray diffraction (XRD) techniques. A microstructure evaluation is employed to justify the homogenous dispersal and the existence of reinforced particles. To ensure the quality and reliability of products made from these alloys, destructive tests are often conducted to evaluate their mechanical properties and behavior under different loading conditions.

In this study, the friction stir extrusion process as a new method was used to produce AA 1050 aluminum composite wires reinforced with silicon carbide (SiC) powder. The effect of process parameters on temperature (T), porosity (P) and ultimate tensile strength (UTS) was evaluated using the response surface method based on the Box-Behnken design. The input parameters included rotational speed (RS), extrusion force (EF) and reinforcement weight percentage (RF). Moreover, the microstructural evaluation of composite samples was conducted using optical microscope and scanning electron microscope. Finally, analysis of variance and regression analysis were used to obtain an appropriate model and confirm the accuracy of the results. The results showed that the temperature was increased by increasing the rotational speed to 1000 r/min and decreasing the extrusion force to 5.5 kN. Moreover, the lowest porosity value (averaged = 0.5%), and the highest tensile strength value (averaged = 153 MPa) were obtained at RS = 750 r/min, EF = 10.5 kN and RF = 3%. This can be attributed to the uniform distribution of reinforcing particles and strong interfacial bonding between SiC particles and the aluminum matrix. Also, the most effective parameter in the process was rotational speed which exhibited the greatest influence on P (53%) and UTS (41%) of composite samples. However, reinforcement weight percentage had the least effect on P (14%) and UTS (28%).

Multimaterial designs consisting of metallic and polymeric material are aimed to reach high lightweight potential. This study presents novel hybrid structures with different interlayer of thermoplastic composites not previously reported in the literature for multi-laminated composites. The metal-polymer-metal hybrids comprise of polyamide 6 (PA6) or polyamide 6,6 (PA66) composite reinforced with 15% of short glass fiber as a sandwich layer. AA7075/AA2124-SiC-17p composite laminates are bonded through hot pressing connection. Mechanical properties of the structures are experimentally investigated from the point of maximum shear strength between dissimilar laminates, resistance to fracture and energy absorbing capacity. Scanning electron microscope (SEM) analysis of fracture surfaces is carried out after mechanical characterization. Short beam three-point-bending tests show that the laminate on which the load is applied is of great importance for the asymmetric hybrid structures. Shear dominant failure is only visible when the bending load is performed from the AA7075 surface. Single-edge notched bending (SENB) test results indicate that there is no significant difference between two configurations in terms of the Mode-I fracture toughness. V-notch Charpy impact tests reveal that the interlayer of PA6 composite contributes to a 13.15% more absorbed energy than that of the PA66 interlayer.
