Impact of carbide-promoting elements on the mechanical properties of solid-solution-strengthened ductile iron
International Journal of Metalcasting - Tập 14 - Trang 365-374 - 2019
Moritz Riebisch, Björn Pustal, Andreas Bührig-Polaczek
Solid-solution-strengthened ductile iron (SSDI) exhibits a unique combination of strength and ductility due to the fully ferritic matrix and the increased silicon content. Steel scrap is the most important feedstock for this material because of its low cost. Since steel scrap contains carbide-promoting elements whose alloy content is expected to increase in the future, there is a need to study the...... hiện toàn bộ
The Influence of the Casting Methods and Variables on the Microstructural Properties of A356–SiC Nanocomposite
International Journal of Metalcasting - - Trang 1-15 - 2024
Mohsen Ostad Shabani, Amir Baghani, Iman Mobasherpour, Mansour Razavi, Mohammad Reza Rahimipour, Esmaeil Salahi
In a comprehensive study, effects of casting methods such as gravity sand casting, squeeze casting and composite casting in semi-solid state and casting variables (i.e., cooling rate, stirring speed and shear forces) on the microstructure, porosity formation and mechanical properties of A356–SiC nanocomposites were investigated thoroughly. First, a step-like sample was used to make the sand castin...... hiện toàn bộ
A Particle-Resolved CFD Model of the Combustion and Gasification Processes of Coke
International Journal of Metalcasting - Tập 12 - Trang 113-125 - 2017
W. Heinbichner, G. Wolf, A. Huster
With the aim of optimizing the processes near the tuyeres of a coke-fired cupola furnace, a mathematical model based on computational fluid dynamics was developed that takes into account the combustion and gasification processes of lump coke at the particle scale. Basic fluid mechanics equations were used for the modeling and were supplemented by additional transport properties. The main task was ...... hiện toàn bộ
Measurement of Elastic Modulus of PUNB Bonded Sand as a Function of Temperature
International Journal of Metalcasting - Tập 4 - Trang 7-18 - 2015
J. Thole, C. Beckermann
The stiffness of molds and cores has a large effect on casting quality in sand foundries. Measurements of the elastic modulus of PUNB bonded silica sand are performed from room temperature to 500C (932F). The measurements are taken almost instantaneously during the heating to capture the changes in the elastic modulus throughout the temperature range. The effect of the heating rate is investigated...... hiện toàn bộ
3D Analysis of Casting Surface Characterization Based on the Variogram Roughness Method
International Journal of Metalcasting - Tập 16 - Trang 1079-1090 - 2021
Daniel Wilhelm Schimpf, Frank Earl Peters
Casting surface specifications are commonly inspected via visual inspection. Since visual inspection is subjective, the results are not very reliable. Objective methods that could replace visual inspection for simple surface patches, and thus increased the reliability of the inspection process has been introduced. This paper continued the work on the variogram roughness method and adopted the meth...... hiện toàn bộ
Progress on the Understanding of Fluidity of Aluminium Foundry Alloys
International Journal of Metalcasting - Tập 2 - Trang 17-27 - 2015
M. Di Sabatino, L. Arnberg, D. Apelian
Fluidity of aluminium foundry alloys plays a key role for aerospace and automotive industries especially when producing thinner and hence lighter casting components. Fluidity is a complex property of the molten metal, which depends on many factors. This paper reports on recent results documenting the effect of important factors such as: casting temperature, grain refinement, alloy chemistry (parti...... hiện toàn bộ
Numerical Analysis of the Cooling System Performance and Effectiveness in Aluminum Low-Pressure Die Casting
International Journal of Metalcasting - Tập 15 - Trang 216-228 - 2020
Hakan Yavuz, Onur Ertugrul
This study was carried out to determine the parameters affecting the performance of ring-type air cooling channels used in low-pressure die casting method for aluminum wheel casting. The main purpose of this study is to reveal the working principles of air cooling used in wheel casting. The study was conducted using computational fluid dynamics software. Field verification was performed before dif...... hiện toàn bộ
Filtration Efficiency in the Recycling Process of Particle-Reinforced Aluminum Alloys Using Different Filter Materials
International Journal of Metalcasting - Tập 17 - Trang 1681-1696 - 2022
Johannes Paul Schoß, Benedict Baumann, Andreas Keßler, Michal Szucki, Gotthard Wolf
In this study, filtration of aluminum alloy (Al) with different weight fractions of SiC particles (SiCp) was investigated. Therefore, three different filter materials of 20 pores per inch (ppi) ceramic foam filters (CFF) were tested. A special three-chamber furan mold was used for the casting trials to provide uniform filling and flow conditions for the filtration process. Samples from sections of...... hiện toàn bộ
Electromigration Effects During Resistance Brazing of Zn–Al/Al System
International Journal of Metalcasting - Tập 13 - Trang 937-943 - 2019
Wei-yuan Yu, Wei-jie Wu, Qiao-li Lin, Xue-min Sun
Liquid filler metals often experience electromigration (EM) effects during resistance brazing due to the high current density, which can affect the microstructure of the joint and reduce its strength. However, to date, few studies have investigated this effect. Here, a Zn–Al alloy filler metal was used to braze 6063 Al alloys using direct-current resistance brazing. We clearly observed that EM occ...... hiện toàn bộ
