“…For the manufacturing of critical parts operating under extreme conditions, aluminum matrix composites can be used instead of aluminum alloys. Aluminum matrix composites have a number of advantages, including high strength properties at both ambient and elevated temperatures [5][6][7][8][9][10][11]. Traditional reinforcing phases in composites are ceramic particles, such as Al 2 O 3 , which are characterized by high hardness and melting temperatures [12].…”

Al2O3 is a traditional strengthening phase in aluminum matrix composites due to its high hardness and melting point. At the same time, zirconium is an important alloying element for heat-resistant aluminum alloys. However, its effect on the structure and properties of Al-Al2O3 composites remains unexplored at present. In this work, the effect of the addition of Zr (5 wt%) on the microstructure and strengthening of the Al-10 vol% Al2O3 composite was investigated for the first time. Composite materials with and without Zr addition were obtained through mechanical alloying as a result of ball milling for 20 h followed by multi-directional forging (MDF) at a temperature of 400 °C. OM, SEM and XRD were used to study the microstructure and its parameters. The work showed that the use of mechanical alloying and MDF contributes to the formation of dense composite samples with a nanocrystalline microstructure and a uniform distribution of alumina particles. The addition of Zr contributes to a 1.4-fold increase in the microhardness and yield strength of a compact sample at room temperature due to the formation of Al3Zr (L12) dispersoids. It was been shown that the largest contribution to the strength of both materials comes from grain boundary strengthening, which is at least 50% of the yield strength. The resulting composites exhibit high heat resistance. For example, their compressive yield strength at 350 °C is approximately 220 MPa.

“…Aluminum is a lightweight material that has formed an integral part of today's 4.0 industry [1]. Its uses in various industries such as beverages, aerospace, and building have made it indispensable [2][3][4][5][6]. However, improvements are still being made to aluminum and its alloys to better its uses, especially in structural applications.…”

“…In recent years, aluminum matrix composites (AMCs) have been widely developed, especially with the use of easily sourced agricultural residue as reinforcement [11]. Furthermore, AMCs have been used in microelectronics, bicycles, and golf clubs due to their high resistance to corrosion and light weight [6,11,12]. The selection of fabrication routes has also been one of the criteria for developing aluminum composites.…”

The need for improved metallic materials in terms of physicomechanical, microstructure, and corrosion properties has necessitated the need to form metal matrix composites. This article adopted the stir casting procedure and used wood particles (WP) to reinforce aluminum alloy at different volume fractions. The corrosion properties of the aluminum matrix in 3.5% wt NaCl were characterized using scanning electron microscopy (SEM), the potentiodynamic polarization curve, and open circuit potential. The corrosion results of the reinforced aluminum alloys was compared with the unreinforced alloy. The unreinforced sample showed improved resistance to corrosion compared to the reinforced aluminum alloy. All samples exhibited visible Pits on SEM observation.

This paper investigates microstructural and mechanical characteristics of novel AA7075 composites supplemented with agricultural waste, i.e. rice husk ash and poultry waste, i.e. carbonized eggshells. Both these wastes possess important constituents which make them potential reinforcement material for composites, and their utilization also reduces the problem of disposal to a certain extent. AA7075 composites with varying weight percentages of rice husk ash and carbonized eggshells were prepared through stir casting route. The sum of weight percentages of both reinforcements was kept constant at 5 wt.%. Composites were tested for density and different mechanical properties. Prior to these tests, composites were examined through scanning electron microscopy and energy-dispersive X-ray spectroscopy techniques, wherein uniform distribution of reinforcements was observed. Inclusion of light weight reinforcements decreased the density of composites. Among these composites, highest hardness value was shown by composite having 5 wt.% of rice husk ash with 24.47% enhancement over unreinforced AA7075. Maximum tensile strength and compression strength were exhibited by hybrid composite with 3.75 wt.% rice husk ash and 1.25 wt.% carbonized eggshells. This increment is 28.20% and 16%, respectively, over base composition. Impact strength decreased as the weight percentage of CES increased, thereby indicating brittleness in behaviour. Fractography analysis of tensile and impact test specimens was done through scanning electron microscopy to determine failure mode wherein presence of cracks, voids, dimples, debonding, etc. was observed. Hence, these light weight and low cost green AA7075 composites showed improved properties making them as an alternative as well as sustainable material for automotive and aerospace applications.
