“…Besides the mechanical test, a chemical composition test was conducted at the Laboratory of Manufacture, Polytechnic State of Semarang, using a universal chemical composition spectrum test (spectrometer) of the Bruker Q2 ION type produced by Bruker Corporation, as seen in Figure 5a. Because the alloy contains specific components that determine its qualities, the test seeks to ascertain its composition [29]. Preparing composition test specimens were under ASTM E1251-17a [30].…”

The aluminium industry for ship materials produces waste material that can pollute the environment. To protect the environment from material pollution, the aluminium waste recycling process can be used to develop ship material. This study aims to analyze the physical and mechanical characteristics of aluminium with magnesium, copper, and zinc addition. Several tests, such as chemical composition, tensile, and impact tests, will be conducted to ascertain the mechanical properties of aluminium alloy. Adding alloy material in the range of 0-10% resulted in various alloy element compositions. It can be analyzed that the aluminium contents decreased with the increase of alloy elements. The highest rise in alloy elements can be found in the addition of magnesium than in copper and zinc addition. Moreover, the mechanical tests showed that aluminium casting with magnesium, copper, and zinc additions influenced the mechanical properties of the aluminium alloy. It can be found that tensile strength and modulus of elasticity values improved with the increase of alloy addition. The addition of magnesium has better tensile properties than the addition of copper and zinc. In contrast, the impact resistance decreased with the addition of magnesium, making the alloy more brittle.

“…Moreover, the quality of semi-solid processed components is much better than that of cast components and close to the quality of plastic formed components. Therefore, semi-solid processing technology has been used to produce high-quality castings without defects or improve the quality of castings in the fields of automobile, motorcycle, bicycle and telecommunication equipment [5][6][7].…”

Review Application of Aluminum Alloy Semi-Solid Processing Technology in Automobile: A Review Hongxing Lu 1, * , Zhengbai Liu 2, and Qiang Zhu 1 1 Department of Mechanical and Energy Engineering, Southern University of Science and Technology, Shenzhen 518055, China 2 School of Innovation and Entrepreneurship, Southern University of Science and Technology, Shenzhen 518055, China * Correspondence: luhx@sustech.edu.cn Received: 15 January 2023 Accepted: 23 February 2023 Published: 17 March 2023 Abstract: Semi-solid processing technology is a new forming technology for aluminum alloy components, which has advantages in producing high-quality components with complex shapes. Several methods of semi-solid metal preparing and forming have been developed in the past 50 years. Some methods have been applied to provide high-quality components or improve castings’ quality in the field of automobile. This paper reviews the development and application of semi-solid processing technology and discusses about its future application prospects.

“…Both wrought and cast aluminum alloy can be used to manufacture various automobile parts [8]. The wrought aluminum alloy has good relative density and mechanical properties, but its high production cost and low production 2 of 25 efficiency limit its wide application [9,10]. In contrast, cast aluminum alloy is more popular due to its low production cost, but the performance of an aluminum alloy produced by the casting process is not so desirable [11].…”

Numerical Simulation and Experimental Validation of Squeeze Casting of AlSi9Mg Aluminum Alloy Component with a Large Size

The squeeze casting process for an AlSi9Mg aluminum alloy flywheel housing component was numerically simulated using the ProCAST software, and orthogonal simulation tests were designed according to the L16 (4) 5 orthogonal test table to investigate the alloy melt flow rule under four factors and four levels each of the pouring temperature, mold temperature, pressure holding time and specific pressure, as well as the distributions of the temperature fields, stress fields and defects. The results showed that the flywheel housing castings in all 16 test groups were fully filled, and the thinner regions solidified more quickly than the thicker regions. Hot spots were predicted at the mounting ports and the convex platform, which could be relieved by adding a local loading device. Due to the different constraints on the cylinder surface and the lower end surface, the solidification was inconsistent, the equivalent stress at the corner junction was larger, and the castings with longer pressure holding time and lower mold temperature had larger average equivalent stress. Shrinkage cavities were mainly predicted at mounting ports, the cylindrical convex platform, the peripheral overflow groove and the corner junctions, and there was also a small defect region at the edge of the upper end face in some test groups.
