Abstract: Metal matrix composite (MMC) focuses primarily on improved specific strength, high temperature and wear resistance application Aluminium matrix reinforced with titanium carbide (Al–TiC p ) has good potential The main challenge is to produce this composite in a cost effective way to meet the above requirements In this study Al–TiC p castings with different volume fraction of TiC were produced in an argon atmosphere by an enhanced stir casting method Specific strength of the composite has increased with higher % of TiC addition Dry sliding wear behaviour of AMC was analysed with the help of a pin on disc wear and friction monitor The present analyses reveal the improved specific strength as well as wear resistance

TL;DR: In this paper, the authors present a review on the state-of-the-art in the utilization of industrial and agricultural waste materials for the development of metal-matrix composites (MMCs), providing an insight into the challenges and opportunities for the exploitation to their full potential.
Abstract: In this contribution, authors present a review on the state-of-the-art in the utilization of industrial and agricultural waste materials for the development of metal–matrix composites (MMCs), providing, through the judicious analysis of an ample and varied references source – from the oldest to the newest ones – an insight into the challenges and opportunities for the exploitation to their full potential. In addition to its topicality, the novelty of this contribution lies in the presentation of key statistical, technical, and property-related information of a comprehensive variety of waste materials classed into two main groups, namely, fly ash reinforced MMCs and MMCs derived from other waste materials. Although fly ash has been exploited in a broad range of applications, the attention paid for its use in the development of MMCs seems to be insufficient. A purposely designed chart helped to pinpoint the more demanding and profitable applications of fly ash, and establish strategic opportunity ar...

TL;DR: In this article, the compressive behavior of eight different metal matrix syntactic foams (MMSFs) is investigated and the results showed that the engineering factors such as chemical compositions of the matrix material, the size of the microballoons, the previously applied heat treatment and the temperature of the compression tests have significant effects on the compression properties.
Abstract: The compressive behaviour of eight different metal matrix syntactic foams (MMSFs) are investigated and presented. The results showed that the engineering factors as chemical compositions of the matrix material, the size of the microballoons, the previously applied heat treatment and the temperature of the compression tests have significant effects on the compressive properties. The smaller microballoons with thinner wall ensured higher compressive strength due to their more flawless microstructure and better mechanical stability. According to the heat treatments, the T6 treatments were less effective than expected; the parameters of the treatment should be further optimised. The elevated temperature tests revealed ∼30% drop in the compressive strength. However, the strength remained high enough for structural applications; therefore MMSFs are good choices for light structural parts working at elevated or room temperature. The chemical composition – microballoon type – heat treatment combinations give good potential for tailoring the compressive characteristics of MMSFs.

Abstract: In this paper processes for fabrication of aluminium-alloy composites containing paniculate non-metals, the net shape forming of these composites, their microstructures, their friction and wear behaviours and their mechanical properties are described. Composites of two wrought (2014 and 2024) and one cast (201) aluminium alloys containing 2 to 30 wt% of Al2O3 and SiC particles in the size range of 1 to 142μm were prepared. The non-metallic particles were added to a partially-solid vigorously-agitated matrix alloy. The particles were then retained in the matrix until interface interaction, for example, the formation of MgAl2O4 spinel in the case of Al2O3 particles, were faciliated. These composites were solidified and subsequently reheated to above their liquidus temperature and formed under high pressure in a closed-die forging type of apparatus. Composites with particulate additions of size larger than 5μm possessed homogeneous structures; particles of size 1μm, however, tended to cluster. The wear behaviour of the composites was studied using a pin-on-disc type machine. It was shown that composites containing large amounts of non-metals, ≈ 20 wt%, exhibit excellent wear resistance whilst those with small to moderate amounts of non-metals possess tensile properties comparable to the matrix alloy. Increasing the amount of particulate additions results in reduced ductility. Finally, a method was investigated of producing components with high weight-fractions of non-metals near their surface.
