“…In as-extruded Mg-Li- Zn-Gd alloys, the dynamic recrystallization in Mg-8Li-3Zn-0.6Y alloy induced the generation of I-phase, which greatly improved the properties of alloys [12] . Different from the thermoplastic forming process, the casting processes are widely used to produce complex castings with high quality, such as permanent mold casting, squeeze casting and rheo-squeeze casting [13] . Among them, the rheo-squeeze casting combines the advantages of traditional die casting and forging technology.…”

“…Thirdly, the morphology, size, and distribution of intermetallic compounds, especially the quasicrystal I-phase, also play a significant role in the mechanical performances. For the permanent cast Mg-12Zn-2Y alloy, the concentration of massive coarse icosahedral Mg-Zn-Y phases leads to stress concentration, offering sources of micro-cracks and causing the decline in the ductility [13] . As to the rheo-squeeze casting sample, the coarse icosahedral quasicrystal disappears and lamellar eutectic structure is refined markedly.…”

Magnesium alloy has the characteristics of low density, high specific strength and large elastic modulus, and is widely used in electronic communication, transportation, aerospace, and other fields [1][2][3] . However, compared with other cast alloys, thermomechanical properties and heat resistance of conventional cast magnesium alloy are lower, which limit the industrial application of magnesium alloy [4,5] . Some researchers have studied the effect of the quasicrystal phase on the mechanical

“…Squeeze casting is both economical and has the potential to create cast components with minimal defects, often achieving near-net-shaped components [31][32][33]. In addition, die-casting reduces the metal wastages which arise due to the use of feeders and risers as in conventional sand casting [34].…”

The automotive industry traditionally reduces weight primarily by value engineering and thickness optimization. However, both of these strategies have reached their limits. A 6% reduction in automotive truck mass results in a 13% improvement in freight mass. Aluminum alloys have lower weight, relatively high specific strength, and good corrosion resistance. Therefore, the present manuscript involves manufacturing Al-based alloy by squeeze casting. The effect of applied pressure during the squeeze cast and gravity cast of a novel Al-Si alloy on microstructural evolution, and mechanical and wear behavior was investigated. The results demonstrated that squeeze casting of the novel Al-Si alloy at high-pressure exhibits superior mechanical properties and enhanced wear resistance in comparison to the gravity die-cast (GDC) counterpart. Squeeze casting of this alloy, at high pressure, yields fine dendrites and reduced dendritic arm spacing, resulting in grain refinement. The finer dendrites and reduced dendritic arm spacing in high-pressure squeeze cast alloy than in the GDC alloy were due to enhanced cooling rates observed during the solidification process, as well as the applied squeeze pressure breaks the initial dendrites that started growing during the solidification process. Reduced casting defects in the high-pressure squeeze cast alloy led to a reduced coefficient of friction, resulting in improved wear resistance even at higher loads and higher operating temperatures. Our results demonstrated that squeeze casting of the novel Al-Si alloy at high-pressure exhibits a 47% increase in tensile strength, 33% increase in hardness, 10% reduction in coefficient of friction, and 15% reduction in wear loss compared to the GDC counterpart.

“…Squeeze casting is an advanced forming technology in which the melt solidifies under high mechanical pressure [1][2]. During the process of squeeze casting, the melt contacts closely with the steel mould under pressure, which increases the heat transfer coefficient and cooling rate of the melt and thus refine the microstructure.…”

The squeeze casting process is an advanced technology, which is suitable for a wide range of alloys including Al-Cu-Mg alloys. The high pressure in squeeze casting process both refines the microstructure and enhances the mechanical property of the alloys. The heat transfer and solidification process are complex with the chilling mould and pressure of machine punch. This results in the inhomogeneous microstructure and property in casting alloy. This study focuses on the distribution of microstructure, chemical composition, and hardness of Al-Cu-Mg alloy along the radial direction of casting. The composition and area fraction of eutectic phases are characterized. Moreover, the relationship between the microstructure and mechanical property was also analysed to show the characteristic of microstructure in squeeze casting process.
