The effect of reinforced SiC on the mechanical properties of the fabricated hypoeutectic Al-Si alloy by centrifugal casting

Optimization of Centrifugal Casting Parameters of AlSi Alloy by using the Response Surface Methodology

“…Then M = 5.105 X 2.7X 1.2 = 16.54 g for the vertical molding and M= 116.72 X 2.7= 315.13 g for the horizontal molding. Now, to calculate the centrifugal forces applied on the inner wall of the rotation mold and by using the maximum calculated angular velocity of the mold (Vm) and the design mass of the melted metal (M) as 16.5 g and the rotational circle radius of the mold = 195mm for vertical mold and = 315 g and the radius of the mold = 36 mm for horizontal mold, then the centrifugal forces applied on the inner wall surface of the centrifugal casting machine is [5]:…”

“…The obtained tensile strengths values were improved by 38.6 and 45.41 %, compared with the gravitational casting, respectively; while the percentage elongations were reduced to 0.281and 0.291 %; which means decreased by 33.45 and 31.69 % for the vertical and horizontal centrifugal casting compared with the values obtained by gravitational casting experiments, respectively.All metals, alloys, nonmetals and virtually any material that can be liquidized and pourable can be cast by centrifugal casting processes for producing an isotropic and a dense product, including carbon and alloy steels, gray and ductile iron, stainless steels, copper, aluminum and magnesium alloys, nickel, cobalt and titanium based alloys and also nonmetals, including plastics, ceramics, glasses [1], by using a stainless steel, cast iron and graphite mold materials [2]. The process has become widely used for producing special castings tubes, pipes, rolls, cylinder liners and other axisymmetric parts [3][4][5]. The final quality of the products is depending upon the rate of solidification, the rotational speeds of the mold and the molten metal flow pattern [5].Centrifugal casting machines are categorized into three designs based on the operating of the mold Surface Methodology…”

Enhancing the tensile strength of SiC reinforced aluminium-based functionally graded structure through the mixture design approach

“…Owing to their better resistance to corrosion and abrasion, improved strength to weight ratio and lower coefficient of thermal expansion, the Al-Si alloys are being increasingly used in multiple applications, like cylinder blocks, heads and pistons (Ali, 2019). The silicon content present in most Al-Si alloys has the ability to reduce the density and coefficient of thermal expansion, which thereby improves its properties in the aspects of hardness, strength and resistance to wear; hence, these alloys are being rapidly used as replacement materials in major fields of automotive, electrical and aerospace sectors.…”
