“…Based on the figures, the average size can be easily calculated, and this also matches well with the size supplied by the particle provider. Given that high-energy ball milling is a common technique for attaining a homogeneous distribution of reinforcements in MMCs [33,34,35,36], this method was also applied in this work to prepared Al MMCs. In the preparation process, as illustrated in Figure 1a, raw powders with the same diameter were firstly milled for 6 hours to form Al-SiC composites with different SiC contents (0, 10, 20 and 30 wt%) and Al-30%SiC/Cu composite with designed Cu content (0, 20 and 30 wt%) in a vertical planetary ball mill with a speed of 200 rpm using 5-mm-diameter corundum balls.…”

In this work, SiC and Cu particles were utilized to enhance the thermal and mechanical properties of Al matrix composites. The ball-milling and cold-compact methods were applied to prepare Al matrix composites, and the uniform distribution of SiC and Cu particles in the composite confirms the validity of our preparation method. After characterizing the thermal conductivity and the compressibility of the prepared composites, results show that small particles have a higher potential to improve compressibility than large particles, which is attributed to the size effect of elastic modulus. The addition of SiC to the Al matrix will improve the compressibility behavior of Al matrix composites, and the compressibility can be enhanced by 100% when SiC content is increased from 0 to 30%. However, the addition of SiC particles has a negative effect on thermal conductivity because of the low thermal conductivity of SiC particles. The addition of Cu particles to Al-SiC MMCs could further slightly improve the compressibility behavior of Al-SiC/Cu MMCs, while the thermal conductivity could be enhanced by about 100% when the Cu content was increased from 0 to 30%. To meet the need for low density and high thermal conductivity in applications, it is more desirable to enhance the specific thermal conductivity by enlarging the preparation pressure and/or sintering temperature. This work is expected to supply some information for preparing Al matrix composites with low density but high thermal conductivity and high compressibility.

“…It should be noted that strengthening mechanisms of the ARBed composites are not exclusively limited to those mentioned earlier for other types of ARB, i.e., ARBed similar or dissimilar sheets; however, they are also attributed to the following items: a. Reinforcement particles acting as barrier against dislocation movement. The first mechanism is the strengthening effect since adding reinforcements to a metal matrix significantly improve mechanical strength due to dislocation pile up around the particles [101,102]. b.…”

Different manufacturing processes can be utilized to fabricate light-weight high-strength materials for their applications in a wide spectrum of industries such as aerospace, automotive and biomedical sectors among which accumulative roll bonding (ARB) is a promising severe plastic deformation (SPD) method capable of creating ultrafine grains (UFG) in the final microstructure. The present review discusses recent advancements in the ARB process starting with the ARB basics, intricacies of the underlying mechanisms and physics, different materials, surface and rolling parameters, and finally its key effects on different properties such as strength, ductility, fatigue, toughness, superplasticity, tribology and thermal characteristics. Moreover, results of recent computational investigations have also been briefed towards the end. It is believed that ARB processing is an emerging area with tremendous opportunities in the industrial sector and ample potential in tailoring microstructures for high-performance materials.

“…Many methods have been suggested in the survey for the preparation of copper matrix composites like stir casting [29], traditional powder metallurgy [30][31][32], hot press [33], friction stir processing (FSP) [34,35], infiltration [36] and spark plasma sintering (SPS) [37,38]. Casting method is a suitable technique for enhancing mechanical characteristics; however, hard in dominant mixing the constituents [39].…”
