Abrasive wear of Al2O3 particle reinforced 2024 aluminium alloy composites fabricated by vortex method

Advance on Al2O3 Particulates Reinforced Aluminum Metal Matrix Composites (Al-MMCs) Manufactured by the Power Metallurgy Techniques- Microstructure and Properties

“…However, Hosking et al [45] had demonstrated a decrease in wear rate of 2024Al/Al 2 O 3 composites with increasing particle size. The same tendency of wear rate with Al 2 O 3 particle size was also observed by Kök et al [51], Roy et al [41] and Capus [52]. They considered that under the sliding wear testing conditions, the main wear mechanism was micro cutting and micro ploughing for the composites containing small particles, whereas it was grinding for the composites containing large particles [53].…”

Mechanical and dry sliding wear properties of silicon carbide particulate reinforced aluminium–copper alloy matrix composites produced by direct squeeze casting method

“…The wear resistance of these alloys can be improved considerably by adding ceramic reinforcements into aluminium, leading to the formation of the metal-matrix composites (MMCs). Incorporation of ceramic reinforcements can result in a favourable combination of the high ductility and the high strength [2,3]. The ceramic reinforcements generally can be in the form of particles, whiskers and fibres.…”

“…During the last two decades, superior wear performance of MMCs reinforced with ceramic particles has been reported [2,3].…”

Nanoscratch-induced deformation behaviour in B4C particle reinforced ultrafine grained Al alloy composites: a novel diagnostic approach

“…Conventional ceramic particle reinforced metal-matrix composites (MMCs) can provide improved mechanical properties due to the combination of the advantageous properties of a metallic matrix and ceramic reinforcements, leading to their increasing importance and application potential in aerospace, defence and automotive industries [1][2][3][4][5][6][7]. More recently, MMCs with a nanostructured (NS) or ultrafine-grained (UFG) matrix have been developed and these materials can exhibit even higher specific strength and enhanced stiffness as compared to their counterparts with coarse-grained (CG) matrices, but often with significantly reduced ductility [7][8][9][10][11][12][13].…”
