Effect of Ablation Casting Process on the Microstructural Parameters and Tensile Properties of A413 and A356 Alloys
International Journal of Metalcasting - - Trang 1-14 - 2023
Mostafa Arabpour, Seyed Mohammad Ali Boutorabi, Hasan Saghafian
The process of ablation casting (AC) is a novel sand casting technique that not only offers the benefits of conventional sand casting (CSC), but also offers opportunities to overcome some of its shortcomings. In this research, A413 and A356 alloys were cast via CSC and AC processes. The CSC simulation process showed that the solid fraction parameter at different times indicated A413 to be more sui...... hiện toàn bộ
Research on Surface Coating Treatment of Casting Die for Copper Alloy Water-Meter Shell
International Journal of Metalcasting - Tập 17 - Trang 922-934 - 2022
Kai-Kui Zheng, You-Xi Lin, Sheng-Qing Yan, Wei-Ping Chen
In the production process of copper alloy metal mold casting, the surface of the mold cavity must bear the effects of erosion wear and thermal stress of high-temperature liquid metal, resulting in fatigue cracks and erosion corrosion on the mold surface, which seriously affects the service life of the mold. To address the problems of short mold life and poor surface quality of castings in the cast...... hiện toàn bộ
Speed of Recalescence as a Measure of Graphite Nucleation in Spheroidal Graphite Cast Iron Castings
International Journal of Metalcasting - Tập 15 - Trang 602-612 - 2020
Mohd. Nadeem Bhat, D. M. Afzal Khan, K. K. Singh
The solidification of spheroidal graphite cast iron (SGI) plays an important role in production of sound quality castings. However, owing to the complex solidification behaviour of SGI, prepouring melt quality evaluation technique such as thermal analysis is used to predict quality of liquid metal by analysing the cooling curve pattern. In this study, an attempt has been made to investigate the ro...... hiện toàn bộ
Austempered Ductile Iron with Dual Microstructures: Effect of Initial Microstructure on the Austenitizing Process
International Journal of Metalcasting - Tập 14 - Trang 717-727 - 2020
Wilson Luiz Guesser, Clarissa L. Lopes, Pedro A. N. Bernardini
This work compares alternatives for the production of high ductility ADI, austempered from an intercritical austenitizing temperature range, with a microstructure of ferrite + ausferrite. Different initial microstructures were selected, including ferrite, pearlite, pearlite + ferrite, martensite and ausferrite. The samples were austenitized within the intercritical zone (795 °C) for different time...... hiện toàn bộ

Tensile Properties Enhancement Response of A413 and A356 Aluminum Casting Alloys to Direct Water Spray Processing
International Journal of Metalcasting - - Trang 1-16 - 2023
Ali Kheirabi, Mohammad Pourgharibshahi, S. M. A Boutorabi, Mehdi Divandari
Direct water spraying (DWS) is an approach similar to ablation casting using direct impingement of water spray on the solidifying casting but is modified in that it no longer relies on eroding removal of the sand bound by water-soluble binders. A removable part of the sand mold is withdrawn during the process, and water is directly sprayed on the exposed casting surface. Two commercial casting Al ...... hiện toàn bộ
Research on Modification of Steel Fiber in Investment Casting shell
International Journal of Metalcasting - Tập 16 Số 4 - Trang 1849-1857 - 2022

Relationship Between Thermal Conductivity and Tensile Strength in Cast Irons
International Journal of Metalcasting - Tập 17 - Trang 2862-2867 - 2023
Vasilios Fourlakidis, Juan Carlos Hernando, Daniel Holmgren, Attila Diószegi
Improved mechanical and thermal properties are important characteristics for enhancing the performance of cast iron components that operate at elevated temperatures. Thermal conductivity defines the temperature distribution within the casting and influences the magnitude of the thermally induced tensile stresses. The microstructural features that increase the thermal conductivity have a negative i...... hiện toàn bộ
Thermal and Microstructural Analysis of an A356 Aluminium Alloy Solidified under the Effect of Magnetic Stirring
International Journal of Metalcasting - Tập 3 - Trang 37-41 - 2015
S. Ordóñez, O. Bustos, R. Colás
The solidification kinetics and microstructural characteristics of an A356 aluminum alloy subjected to magnetic stirring during solidification was studied by metallographic and thermal analyses. The alloy was heated to 680°C (1256°F) and poured into molds held at 200°C (392°F). Some samples were allowed to solidify in a conventional manner, whereas other samples solidified while under the influenc...... hiện toàn bộ
