“…It is used mainly for making pipes, tubes, bushings, cylinder sleeves (liners), gun barrels, sleeves, rods, rings, etc. [6][7][8][9][10]. Vertical centrifugal casting machine is essentially a pressure casting technique, where the mold is rotated in a vertical axis.…”

“…It must be constructed to withstand static and dynamic loads imposed on it, where the dynamic loading is the most critical, thus the machine must be fastened and centered. It produces a non-cylindrical (or even nonsymmetrical) parts with high dimensional accuracy and high strength and then enhances the quality [8,9]. This method is used for casting of parts with too thin sections or for large diameters or short lengths like gears, piston ring, impellers, propellers, bushings, railway wheels, the turbine vanes and blade in an aircraft jet engine, cams and levers in automotive control panels and jewelry.…”

Centrifugal casting is one of the advanced casting branches widely used in the metallurgical industry in which the centrifugal force helps strengthen the workpiece material. The present work attempt to study the effect of the horizontal and vertical centrifugal casting parameters included the centrifugal mold rotation speeds and G-factors values on the quality of the product. The work has been completed with design and fabricated of a low cost horizontal and vertical centrifugal casting machine with the main accessories for producing a hypoeutectic aluminum silicone (AlSi) alloy (content 10 % Si) specimens. The experimental results were analyzed and improved by using the statistical computer program "Design Expert 11" and response surface methodology (RSM). The results showed that for vertical and horizontal casting processes, the finest surfaces quality was achieved when working at mold rotation speed from 520 to 690 and 950 to 1230 RPM, i.e., with an average value of the G-factor = 69 and 50, respectively. The proof stress values were increased with increasing the mold rotation speed up to (690 RPM) and (1230 RPM) or used the G-factor value of 87.99 and 60.96 gave an increase in proof stress by 6.7 and (20.62% for vertical and horizontal casting experiments compared with gravitational casting, respectively. 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

“…Zhang and Wang [6]have proposed thermal bonding lamination method for producing a polymer FGMs having a closed cell and an open cell under the enforced compressive load, controlled heating and suitable holding time. Galy et al [7]have investigated the horizontal centrifugal casting using SiCp+Al concept of FGM to produce multifunctional components of metal matrix composites. They have considered dissimilar mass fractions (0%, 2.5%, 5%, 7.5%, 10% and 15%) of SiCp having element size 16µm, 23µm and 500µm and three rotational speed 800 rpm, 900 rpm and 1000 rpm.…”

A hollow cylinder or a pipe is a common element used in structural applications. Now days in the era of new material development, replacement of consventional materials by modern material are of primary choice for the researchers and developers as well. This paper presents the bucking analysis of functionally graded natural-fiber-flyash-epoxy (FGNFFE) hollow cylinders using FEA. In the first part, a mathematical model for buckling analysis is developed to get the dynamic behavior of hollow cylinder under free vibration. Initial five modes of buckling analysis are performed by theoretical, finite element analysis and experimentation. Accordingly Mechanical properties are obtained and used for buckling study in FEA environment as being a cylindrical structure to the design, it is subjected to compression and buckling due to self weight and due to external load is very common. The critical buckling load is determined by FEA study and compared with the experimental value. Further the study extended by optimizing the critical buckling load and stress with respect to the ingredients and other designed parameters and discussed.

“…Examples powder metallurgy, thermal spray, slip casting, centrifugal casting, laser cladding and chemical vapor deposition [8]. Because of its advantages like low processing temperature vis-a-vis melting techniques, good distribution of reinforced particles and ability to manufacture near net shape products at low cost, powder metallurgy is a good technique for producing MMC's [9][10]. To find the constituents, present in the blended powder and to identify any reactions between the alloy and ceramic components XRD analysis is carried out [11][12].…”

This research focuses on manufacturing and mechanical characterization of functionally graded materials using powder metallurgy techniques. Owing to its low density and high strength to weight ratio, pure aluminum with mesh size No. 200 is chosen as the matrix. Silicon carbide with mesh size No. 220, which has a wide range of applications due to its high hardness, is selected as reinforcement. Specimens of two functionally graded materials(FGM) with 4 layers (0%, 3%, 7%, 10%)(FGM-1) and 5 layers (10%, 20%, 30%, 40%, 50%) (FGM-2) are sintered by varying the SiC composition from layer to layer. From the microstructure, it is clearly evident that four layered specimens achieved more homogeneous mixture than five layered. Also, mechanical properties of four layered specimens attained better results than five layered specimens.
