“…However, when the temperature was higher than 580°C, some Al powders melted due to the local high temperature. The similar phenomena were also reported in the fabrication of Si p /Al composites (Yu et al , 2012) and SiC p /Al composites (Yang et al , 2005). And the melting point of the investigated composites is around 577°C from the Al-Si binary phase diagram (Murray and McAlister, 1984), which is consistent with the experimental results.…”

Purpose Serpentine is usually added into the lubricant oil to form a self-repairing protective layer on worn ferrous surface. But few works have paid close attention to the preparation of composites with the addition of serpentine. In this work, serpentine reinforced Al matrix composites were successfully prepared to be industrial lubrication components. And its fabricating parameters, compressive strength and tribological properties were analyzed. Design/methodology/approach An MM-W1 three-pin-on-disk apparatus was used to investigate the tribological properties. The worn surface, microstructure and cross-sectional morphologies were characterized by scanning electron microscopy equipped with energy dispersive spectroscopy. The compression test was carried out on a universal testing machine. An X-ray diffractometer was used to investigate the phase constitutions. The decomposition temperature of serpentine powders was investigated by a thermal analyzer, which allows simultaneous differential scanning calorimetry and thermogravimetry. With the help of finite element method model, a diagrammatic model of the self-repairing surface layer was developed to analyze the anti-friction mechanism. Findings Through evaluating density and Brinell hardness, sintering at 560°C for 3 h are the appropriate parameters for fabricating the composites. Compressive strength was increased by the addition of serpentine. A self-repairing surface layer was formed, reducing the friction coefficient. And a diagrammatic model of the self-repairing surface layer was developed to analyze the anti-friction mechanism. Originality/value Serpentine was added in fabricating the Al matrix composites for the first time. Sintering parameters were optimized to make better Al/Si/serpentine composites. Compressive strength was increased by the addition of serpentine. A self-repairing surface layer was formed, reducing the friction coefficient under the dry sliding condition. And a diagrammatic model of the self-repairing surface layer was developed to analyze the anti-friction mechanism. It is hoped to be helpful in further confirming the factors for the formation of the self-repairing surface layer, and in designing a new industrial anti-friction composite used for dry sliding conditions.

“…Aluminium matrix composites containing silicon particles are attractive packaging materials for microelectronic applications, as their CTE can be reduced relative to pure aluminium, their thermal conductivity remaining high. By SPS at 510°C, nearly fully dense Si–Al composites were obtained [133]. A composite containing 45 vol.-% Si showed a good combination of properties: an average CTE of 12.7 10 −6 K −1 and a thermal conductivity of 113 W m −1 K −1 .…”

Aluminium and magnesium matrix composites are attractive lightweight materials with strength surpassing that of the corresponding matrix metals. Recent years have seen extensive research aimed at finding ways to control the structure of metal matrix composites and obtaining materials with new sets of properties. This review aims to show that field-assisted sintering is a promising approach for the powder metallurgy processing of aluminium and magnesium matrix composites. The review focuses on the achievements in the compositional and microstructural design and properties of aluminium and magnesium matrix composites obtained by spark plasma sintering, microwave sintering and induction sintering. Issues related to the process scale-up in the field-assisted sintering technologies are also addressed.

“…This results in a simultaneous application of spark plasma and spark impact pressure, thereby enhancing the electric-field diffusion process [166]. Thus, effective sintering at the peak sintering temperature is made possible, and the entire process gets completed within a few minutes [167]. High thermal efficiency, purification of the surface of the particles, rapid sintering of products to near theoretical density, etc., are some prominent characteristics of SPS [168].…”

Monolithic components are often insufficient when a combination of conflicting properties, or a variation in properties at different regions within a material is required. Functionally graded composite materials (FGCM) are a relatively new class of materials with a systematic variation of the composition, microstructure, and properties along one direction. The graded structure offers tailorable property combinations not achievable with monolithic composites and significant recent research has been carried out on their development. An effort has been made in this article to review the latest developments on bulk FGCMs since 2015. The different processing techniques used for their fabrication have been discussed, highlighting their advantages, limitations, and recent advancements pertaining to FGCM fabrication. Various physical, mechanical, and thermal properties of FGCMs have been treated separately, and wherever possible, summary plots combining data from various research articles have been developed. Finally, potential areas for directing future FGCM research have been identified.
