Marble dust is a construction waste material from the processing of marble producing rocks. In this work, the usability of waste marble dust as a reinforcement in the development of Aluminium Metal matrix alloy has been investigated for use in bearing application. The flexural strength and SIF kept onincreasing continuously with increase in reinforcement content up to 10 wt% marble dust while Compressive strength and impact strength showed improvement for the marble dust concentration. Engine bearings are used under increasingly severe temperature and loads. In various condition there isproblem of low fatigue resistance for this Aluminium Metal matrix alloy with the use of marble sludgein bearing production is defined. This paper presents the marble waste powder in various ranges, resulting in higher compressive power, tensile splitting strength and bending strength as specimens. As review, Stir Casting can be used to make this composite and can evaluate its mechanical properties, thermo-mechanical behavior by different methods. [ABSTRACT FROM AUTHOR]

The paper presents the data of optical microscopy of aluminum cast alloy ER4043 fabricated by wire-feed electron-beam additive manufacturing (WEBAM) and samples of composite material made by simultaneous double-wire feed EBAM with the introduction of 5% and 10% of the nickel alloy Udimet-500. The data obtained testify to the complex and heterogeneous structure organization in composite materials made of dissimilar metals with different melting temperatures and densities. The data indicate the presence of non-melting nickel alloy on one side and overheating of aluminum alloy on the other side. [ABSTRACT FROM AUTHOR]

Aluminum alloys have seen substantial growth in application in the industrial industry in recent years. This is due, in large part, to its ability to integrate lightweight and sturdiness in a single material. Over some decades, Aluminum alloys have been made to develop aerospace applications like aircraft material structures due to their lightweight and higher strength. Aluminum is a less expensive and high-performance material with low manufacturing costs. In this context, understanding the properties of aluminum alloy applications is critical for providing industries and scientists with data that enables them to make the best choices for using this amazing metal. This study aims to give the most recent advances in Al-based alloys like the 2000 series, 7000 series, and Al-Li alloys that have been produced for an aviation sector and have excellent benefits. The characteristics and effectiveness of new advanced 2000, 7000 series Al- Li alloys and aluminum alloys are described and compared to currently available alloys. [ABSTRACT FROM AUTHOR]

The experimental research article focuses on determining tensile properties of Aluminum 5154 alloy reinforced with 5% weight fraction of Sic, 5 % weight fraction of TiB2 and 2.5% weight fraction each of SiC and TiB2, fabricated by stir casting method. The effect of the reinforcements on mechanical properties like tensile strength and tensile modulus are evaluated and compared with Al 6063 and Al7075 alloys. TiB2 reinforced composite exhibited superior tensile properties. [ABSTRACT FROM AUTHOR]

The usage of aluminium as an alloy has great demands in the construction, aerospace/aircraft, especially in the automotive sector. Almost all frames and engine construction are made of aluminium alloy. The advantages of aluminium include its lightweight metal, corrosion resistance, good electrical conductor, easy integration with other metals, and machinability. Al-Si alloys in the automotive sector, such as conditional pistons are very suitable because of their wear resistance, corrosion resistance, and lightness properties. This study aimed to identify the effect of adding copper to the Al-Si alloy to obtain the Al-Si-Cu alloy, which was expected to provide mechanical strengthening and microstructure from the stir casting process. The mechanical toughness test results showed an increase in toughness at the addition of 1.5 wt% with a value of 0.0977 J/mm2. Simultaneously, the raw material had a value of 0.0707 J/mm2, gradually decreased with the addition that exceeded 1.5 wt%, namely 2.5 wt% addition resulted in a value of 0.0661 J/mm2, and the addition of 3.5 wt% with a value of 0.0578 J/mm2. The formed microstructure showed continuous smaller granules with increasing Cu percentage, while the dendrites had slender characteristics that increased with increasing Cu percentage.
