The microstructure and properties of Al-matrix composites are directly determined by ceramic particles in the matrix, such as synthetic methods, morphologies, sizes, interface, etc., especially the distribution of particles. Hereinto, Al-matrix nanocomposites, which show brilliant, comprehensive properties, have been widely studied. How to give full play to its advantages in further applications in automotive and aerospace areas has attracted considerable attention from researchers. In this review, current development on the pre-distribution of reinforcement particles and deformation processes and microstructure, mechanical properties of Al-matrix composites reinforced with in-situ and ex-situ nanoparticles will be addressed. In addition, the corresponding development prospects and challenges of nanoparticles reinforced Al-matrix composites fabricated by a combination of pre-distribution and deformation were also summarised.

“…In situ composites offer advantages such as uniform distribution of reinforcement particles, finer grain, clearer interface, improved thermal stability, and costeffective processing. [12][13][14][15][16] Several studies have been conducted on the wear behavior of Al-Mg 2 Si composites, with a focus on factors such as load, sliding speed and distance, temperature, fabrication process, and wear disc material. [17,18] Most of these studies have concentrated on room-temperature dry sliding wear analysis, evaluating the effect of modified or unmodified Al-Mg 2 Si composites fabricated through various processing.…”

This study investigates the wear characteristics of Al–25Mg2Si composite synthesized via gravity casting. The research aims to understand the influence of applied load, test temperature, contact condition (dry and lubrication), and sliding distance on wear characteristics. Results show that higher loads and temperatures lead to increased wear loss and coefficient of friction. The worn surface morphology for higher loads and temperature shows deeper scratches and grooves, indicating severity in wear. The debris size and volume increase with an increase in load and temperature. The dominant mechanism is abrasive, adhesive, and oxidative for both the room‐ and high‐temperature dry sliding conditions. However adhesive and oxidative wear increase with the increase in test temperature. Abrasive wear is the only wear mechanism present during the lubricating sliding condition. Wear transition is noticed during the wear map analysis subjected to load, temperature, and sliding distance. In the case of room‐temperature test, severe–moderate–mild wear transition occurs with the increase in sliding distance and mild–moderate–severe wear transition occurs with the increase in test temperature and applied load. The roughness of the worn surface increases with an increase in applied load and temperature and the use of lubricant hugely reduces the surface roughness.

Evaluating the Effect of Hot‐Rolling Reduction on the Mechanical Properties of In Situ Formed Aluminum–Magnesium–Silicon (Al‐Mg₂Si) Composites

The effects of hot rolling on the microstructure and mechanical properties of as‐cast Al‐15Mg2Si, Al‐20Mg2Si, and modified Al‐15Mg2Si in situ composites are studied. During rolling, the primary and eutectic Mg2Si particles undergo mechanical fragmentation and move along the rolling direction, which results in the enhancement of ductility of the composite compared to the as‐cast state. At high reductions in thickness, however, severely elongated grains and some cracks are observed in the matrix, which are related to the retardation effect of the widely dispersed particles and also fast cooling of sheets during rolling. These effects are found to be responsible for the observed high tensile strength and low ductility of heavily rolled sheets. It is revealed that the strength–ductility balance of the hot‐rolled sheets, as measured by the tensile toughness, is inferior compared to that of the commercially pure Al sheet as the basis for comparison. Therefore, relatively low reductions in thickness are recommended for processing of these composites. The hot extrusion of these composites is also briefly discussed, and it is characterized as a viable route for processing of these composites to achieve high tensile strength with acceptable ductility.
