Corrosion of Aluminum Metal Matrix Composites: A Review of the Effect of Manufacturing Processes, Processing Routes and Secondary Phases

“…Mechanical properties obtained in unreinforced materials using this method are the same as those identified in conventionally produced versions of the same alloy. Al/SiC composites produced by hot isostatically press has been observed to poses about 2.5% higher degree of densification than extruded counterparts [46]. This difference did not result in an improvement in ultimate tensile strength for the hot isostatically press (HIP) samples but transition electron microscopy (TEN) result show severe deformation of SiC particulates by neighboring particulates in the HIP samples.…”

Effect of Al2O3Content and Milling Time on Microstructure and Mechanical Properties of Aluminum Metal Matrix Composites

“…The main problem with aluminum and its alloys is significant loss of self‐properties at high temperatures 6,7 . To increase the resistance of these materials at high temperatures, aluminum metal matrix composites (Al‐MMCs) have been produced by adding high‐temperature‐resistant oxides such as Al 2 O 3 , ThO 2 or Y 2 O 3 as reinforcement components 8–10 . Al 2 O 3 fibers and particles are the most commonly used reinforcements in MMCs 11 .…”
