Thank you so much sir Prof. Yuri Mirgorod for your suggestions.

Dear Dr. Neeraj Kumar Bhoi,

the MMCs (Metal Matrix Composites) generally consist of an heterogeneous system where a non-metal phase is dispersed in an alloy. They can be theoretically customized to specific applications by just changing some qualitative-quantitative parameters of the matrix and of the reinforcing phase. Such composites, having a lower density than the matrix, generally show higher mechanical properties, which make them economically competitive for special uses (for example in the aeronautical and automotive fields). In these applications indeed, a decrease in density, obviously leads to a lower fuel consumption and higher performances, which is a very important parameter. However, in order to improve their reliability, their corrosion resistance properties need to be ascertained, through a detailed analysis of the type of material and likely interactions in aggressive environments. In fact, the heterogeneity of the material could compromise its service life owing to corrosion attack. The characteristics of the composite are strictly linked to different factors: porosity, precipitation of intermetallic phases that can be cathodic in respect to the matrix, formation of reaction products at the matrix-particle interface, matrix composition and characteristics of the reinforcement (type, amount, shape, etc.). You should have the physical-mechanical characteristics required of your product or a material to refer to and try, acting on concentration, size, dispersion, etc. of your reinforcing phase (in first is more simple, for obtain anisoptropic characteristic, you can use particles as reinforcing phase), to achieve an equal or better result.

Pierluigi Traverso Thank you so much, sir, for your suggestion.

Dear Neeraj,

Aluminium alloy-based metal matrix composites (AMMCs) have been by now established themselves as a suitable wear resistant material especially for sliding wear applications. It should pass in the mictrstructure, sliding wear tests, high stress wear abrasion tests, and worn surface studies. The material intrinsic surface properties such as hardness, strength, ductility, work hardening, and so forth are very important factors for wear resistance, but other factors like surface finish, lubrication, load, speed, corrosion, temperature and properties of the opposing surface and so forth are equally important. Development of the secondary processes for MMCs: ‘need of the hour’.

Al-based metal matrix composites (AMMCs) remained as the most potential candidate to be researched on for making engineering components viably. When the question of viability arose, from the different methods adopted for making AMMCs the liquid metallurgy route stood ahead due to its ease of fabrication; although the other routes were more efficient regarding property attainment and micro-structural features, still the ease of fabrication added to the cost economics made the liquid metallurgy route a competitive and viable method.

Potential applications-

1. Advance applications in automotives

2. Metal matrix, fibre–metal and ceramic matrix composites for aerospace applications

3. In many structural and engineering applications

@ashish thakur, Thank you sir for your suggestions and sharing the information.

Potential application of AMCs can be read as potential replacement to aluminum alloy components. Some aluminum alloy components have been replaced with aluminum composite in the last decade particularly in automotive sector. Carry out an industrial survey to find such composite components. Also make a list of components which are still manufactured by various aluminum alloys. If facilities are available in your laboratory, produce such components using aluminum composite material by appropriate choice of matrix, reinforcement and production method. Evaluate the performance of the composite component and compare to existing unreinforced component. If the composite component performs well and fulfills other industrial criteria, it means that a potential application has been identified and developed. Please refer the following articles.

Dear Dr. Neeraj Kumar Bhoi,

Just to complement the very good responses that the previous colleagues have posted, let me add that AMMCs have also very promising applications in mechanical damping, e.g., vibration and noise could be reduced significantly reduced using AMMCs as damping materials due to their viscoelastic properties. Please, see attached paper:

Viscoelastic behavior of a novel aluminum metal matrix composite and comparison with pure aluminum, aluminum alloys, and a composite made of Al–Mg–Si alloy reinforced with SiC particles, Journal of Alloys and Compounds 744 (2018) 445–452.

Hope this is useful,

Jose Ignacio Rojas Gregorio Thank you, professor, for your suggestion.

By density and mechanical properties required/already in use ... tailor MMC with reinforcement content for fine tunning around those values

Dear Sir, Mahmood Khan

Potential applications of the aluminium matrix composites (AMCs), could be identified by finding the direct applications of the monolithic aluminium alloy being used as the matrix metal, for the AMCs. The need for the improvement in the physical and mechanical properties of the monolithic alloy, is the pressing need of the hour, for development of these metal matrix composites.

very well explained @ Ebenezer Jacob Dhas D.S. ....

AMCs are used mainly to replace Al components in different sectors like automotive, aerospace etc. They are also used to replace other metals and alloys credited to their high strength to weight ratio.

AMC undergo heat treatment will exhibit best properties that suits the applications

Prof. Rajesh A M ,

Thank you for your suggestion regarding the application of AL-MMCs. Is it possible to heat treat all kind of Al-MMCs? Specifically, some of the Al compounds are non-heat-treatable. How to overcome such limitations in Al-MMCs.

Thank you.

Dear Neeraj,

Al-based metal matrix composites (AMMCs) remained as the most potential candidate to be researched on for making engineering components viably through the liquid metallurgy route due to its ease of fabrication. Even if the other routes are efficient regarding property attainment and microstructural features, still the ease of fabrication added to the cost economics made the liquid metallurgy route a competitive and viable method.

Identification of potential selection of Al-MMC

Identification for potential application of this composites should be based on the cost factors, ease of fabrication, second phase’s nature, shape, size, distribution, wetability between matrix alloy, less vibration, easy joining and machining, and second phase all have to be considered for making a final choice depending on the component selected, mainly its working conditions for the engineering component to be fabricated. ****Some areas where research is still needed before these versatile composite materials see the light of the day as engineering components include machining, joining, repeatability of properties on mass production, and effect of secondary processing.

The material with better property needs to be converted to a component with better properties than presently available and here lies the challenge, like (i) cast AMMCs will seldom find use as engineering components, (ii) advantages accrued in cast composites do not always hold good when processed, (iii) moreover secondary processing of composites has its own set of challenges, and (iv) only selected alloying elements and second phase dispersions can withstand the rigours and give meaningful results. Application point of view, AMMCs include Swash plate, tennis racket, transfer bench, foot rest, and a few automobile components like brake drum, casings, head light combos, mining equipments, and a few components for structural applications, with an intention to replace either cast iron products or Al-alloy products presently used especially aimed at weight reduction, strength, stiffness, and energy efficiency. However, the aerospace industries, automobile and railway sectors are keenly observing the composite research development. Another point is that all engineering components will undergo somewear related degradation with use even in an otherwise nonwear environment. As we know the The mechanism of wear is in general very complex mainly due to the number of contributing factors to material removal.
