“…The effect of reinforcing Al matrix with a different particles size of 10 AlMg was investigated and the results showed that decreasing the particles size of 10 AlMg leads to increase the density of the composite material. 20 Hafed Ibrahim et al. studied the effect of cobalt activator addition on the density of W-25Cu composites.…”

In this research, 10, 15, 20, and 25 wt.% of WC-TiC-Co particles were coated with a nano-particles layer of copper by the electro-less deposition technique. All the composites were compacted at 900 MPa, and then sintered at 1000 and 1100℃ for 120 min in a hydrogen atmosphere furnace. Nano-composites, which sintered at 1100℃ exhibit relative density higher than those sintered at 1000℃. To investigate the crystal structure and chemical composition of the WC-TiC-Co powders, XRD was used. SEM and EDAX analysis for the sintered samples were performed to investigate the microstructure and morphology of the composites. The relative density, hardness, electrical conductivity and yield stress based on the results of the hardness values were studied. The results revealed that the relative density, hardness, and the yield stress based on the results of the Vickers hardness were improved by increasing the WC-TiC-Co content. On the other hand, the electrical conductivity was decreased by increasing the WC-TiC-Co content.

Due to the increased demand for aluminium and the prohibitive cost of producing primary aluminium, the process of making AMCs using recycled aluminium alloy as a matrix and silica sand tailing without leaching as a filler is essential to be developed. For more cost-effective, the purpose of this study is to make particulate aluminium composite matrix AMCs with a matrix of recycled aluminium and reinforced with silica sand tailing without leaching. This research involves the effect of differences in grain size and filler weight percentage on matrix Al-ZnSiFeCuMg recycled aluminium alloy powder. This study used powder metallurgy technology as well as two-way hot-compaction (300°C) and applied a sintering temperature of 550°C. Density, hardness, and wear testing, as well as microstructure analysis, were conducted to determine the characteristics of the resulting AMCs. An increase in hardness of 67% was achieved by the AMCs-164 µm-20%SiO2 specimen, which used a filler grain size of 164 µm wt.20%. Meanwhile, AMCs-31 µm-20%SiO2, which used a filler grain size of 31 µm, only increased by 63%. The wear test result also showed a lower wear rate achieved by the AMCs-164 µm-20%SiO2 specimen. The results analyses using SEM-EDS instruments showed higher agglomeration and porosity in specimens using a filler grain size of 31 µm, while AMCs using a filler grain size of 164 µm showed an even spread of filler powder. Therefore, AMCs that used 164 µm powder-sized fillers have a stronger bond between the filler and the matrix and produce AMCs that are harder than AMCs that use 31 µm fillers.

The effect of reinforcing particle size on microstructure, relative density and indentation of Mg reinforced by 0, 1.5, 3, 5 and 10% volume fractions of nano- and micro-sized B4C was investigated. The composites were fabricated through powder compaction technique at strain rates of 1.6 × 103 s−1, 8 × 102 s−1 and 8×103 s−1 using split Hopkinson bar, drop hammer and Instron, respectively. The results indicated that the size of B4C and loading rate had significant effect on relative density. For example, the relative density of Mg-10 vol.% B4C nanocomposite was around 2.5% higher than that of its corresponding microcomposites. The relative density of the samples produced at high rate of loading was in average 1.2% higher than that of the samples fabricated quasi-statically. The results of indentation tests on the produced nanocomposite and microcomposite samples also revealed that loading rate and B4C particle size had significant effect on strength of specimens. For example, for Mg-5 vol.% B4C, the maximum load in load–depth curve of the specimens produced by split Hopkinson bar increased from 530 N for micron-sized B4C to 780 N for nano-sized B4C, around 45% improvement. Moreover, nanocomposites had better indentation resistance compared to similar micro composites fabricated using the three methods.
