Fabrication and characterization of BSCCO-2212 tube prepared by centrifugal casting

Growth Speed and Substitution Effects on Alignment and Thermal Transport Properties of Bi-2212 Textured Superconductors

“…doped samples in the same conditions they reduced down to 9.1x10 4 A/cm 2 and 9.48x10 4 A/cm 2 for the G15 and G30 rods, respectively. For the perpendicular case, mag c J ΙΙ (5 K) values of pure samples, at zero applied field, were calculated to be 1.80x10 5 A/cm 2 and 1.68x10 5 A/cm 2 for the G15 and G30 rods, respectively.…”

“…Because of this peculiarity, a lot of attention has been mainly focused on texturing of polycrystalline cuprate superconductors by applying various melt processing methods, i.e. floating zone, melt casting and hot forging routes [3][4][5].…”

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

“…To ensure the efficiency of the performance, all major components of the fabricated horizontal and vertical centrifugal casting machines were designed to withstand the applied static and dynamic loadings to resist the effect of imbalance forces associated in the mold during spinning action. The design analysis included, the centrifugal forces, the powers, and torques generated by the spinning parts and other design calculations considered in the following items [1,4,17].…”

“…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…”
