“…Recently, attention have been channelled towards the use of metallic materials such as pearlitic steels, stainless steel, iron, copper, nickel, titanium and metallic glasses as principal reinforcement in MMCs (Iglesias, Jim enez, Berm udez, Rao, & Chandrasekar, 2013;Sankaranarayanan, Jayalakshmi, & Gupta, 2012;Ye & Liu, 2005). Hard metallic phases are considered as reinforcements because of their inherent ductility and toughness.…”

The growing application of metal matrix composites (MMCs) in structural and reliability critical applications has placed higher premium on good combinations of strength, ductility and toughness, in which ceramic reinforced MMCs currently face limitations. Metallic reinforcements have hence come under consideration as replacements of ceramics due to their good wettability and inherent ductility and toughness. This review covers the use of metallic reinforcements in Al, Mg, Cu and Zn-Al metal matrices and the mechanical behaviour of the developed composites. The performance advantages and some concerns with the use of these alternative reinforcements are also highlighted, and the future possibilities in optimizing mechanical performance of MMCs are posited in the paper.

“…This has resulted in the exploration of more low-cost reinforcement options for development of MMCs in general and Zn-27Al based composites in this specific instance. Recently, the use of steel machining chips as reinforcement has been reported [12][13]. Its choice as reinforcement is predicated on economics, waste management and metallurgical considerations.…”

“…Mechanical behaviour and machining mechanics, explains that steel chips due to the large shear strains associated with the chip formation process possess ultra-fine/nanostructures which impart exceptional mechanical properties compared to the bulk metal [14]. The use of steel chips as reinforcement has been explored in Zn, and Cu-based MMCs and the indications are that it could be utilised to solve the often low fracture toughness and ductility challenges associated with the use of ceramic-based reinforcement [13] [14]. In Zn-27Al based composites, its bearing properties are very crucial in most of the applications it is utilised.…”

<p class="AMSmaintext"><span lang="EN-GB">The prospect of enhancing mechanical, corrosion and wear properties of Zn27Al alloy based composites reinforced with steel machining chips by graphite addition was the focus of this investigation. Double stir casting was used to produce Zn27Al alloy based composites with 7 wt.% reinforcement but with varied compositions containing 1, 2, and 3 wt.% graphite, steel chips making up the balance. Microstructural analysis, mechanical, corrosion and wear tests were used to characterize the composites. The results show that the hardness of the composites decreases slightly with increase in graphite content in the reinforced composites. The tensile strength and fracture toughness of the composite only showed improvement with the addition of 3 wt.% graphite in the hybrid mix (steel chips and graphite) compared with the use of lower graphite content in the mix and steel chips only. The percent elongation did not show dependency on the composition of the reinforcement phase and was basically within the range 6.0 - 6.8 %. The fracture surfaces of all the composites were essentially rough, a preponderant feature of ductile fracture mode. The wear index of the composites was generally low indicating good wear resistance. However, despite the seeming self-lubricating advantage of graphite, the wear resistance of the composite reinforced with only steel chips was relatively better than that of the hybrid graphite and steel chips reinforced composite compositions. Finally, the steel chips and graphite reinforced Zn-27Al alloy based composites were generally more corrosion resistant in 3.5% NaCl solution compared with the unreinforced Zn-27Al alloy.</span></p>
