“…The deformation inhomogeneity shows a difference in the microstructure and the mechanical properties of the processed materials [4]. The ECAP technique has been broadly investigated and analyzed using many different metals and their alloys [24][25][26][27][28][29][30][31]. The purpose of this study is to provide a more detailed mapping of the ECAP process through numerical modeling to study the effectively induced stress-strain behaviors and their distribution after multiple passes of ECAP processing of commercially pure aluminum.…”

Al-based composites reinforced by high volume fraction ceramic particles have attracted much attention because of their high specific strength, high specific modulus, good wear resistance, and low thermal expansion properties. The preparation technology, advantages, and disadvantages of Al-based composites reinforced by high ceramic content are reviewed in this study. The research status of the microstructure and mechanical properties of Al-based composites reinforced by high ceramic particles content is summarized. The effects of ceramic content and preparation technology on the properties of Al-based composites are described. The strengthening mechanism of micro-nano-scale ceramic particles in composites is also expounded. The development trend of micro-nano-scale high content ceramic particle-reinforced Al-based composites is prospected.

In this study, the impact of heat treatment and Equal Channel Angular Pressing (ECAP) processing routes on refining the microstructure, hardness, and corrosion resistance of Al-7.5% S alloy in a 3.5% NaCl solution was examined. The alloy underwent T5 and T6 heat treatments, followed by ECAP processing via routes A and Bc in a mold with a channel angle of 120° at room temperature. The results indicate that dendritic α-Al grains transformed to globular and fiber shapes after processing routes Bc and A, respectively. Both processing routes fragmented coarse and brittle Si particles into smaller sizes in the eutectic phase. The use of a combination of heat treatment and the Equal Channel Angular Pressing (ECAP) process significantly improved the hardness and corrosion resistance of the samples. The hardness of the heat-treated samples increased considerably from 68 to 116 and 129 HV after three and four passes, respectively. Reducing the area ratio between the noble silicon particles and the less noble eutectic aluminum phase greatly enhances the resistance of alloy to pitting corrosion.
