“…Magnesium alloy has several advantages, including a low density, high specific strength, and ease of recycling, etc. It has a broad range of applications in aerospace, railway transportation, automobile industry and other fields due to its good energy-saving and emission reduction effect [1]. In addition to having the requirement of strength for new generation of metal structure materials, magnesium alloys also have the aspect of impact toughness as an important performance index, which directly affects the use of the material performance as well as structural safety and reliability.…”

In this work, the effect of trace Al on the microstructure and mechanical properties of Mg-6Zn alloy was studied. The results show that the as-cast ZM60 alloy consists of α-Mg phase and Mg51Zn20 phase. After the addition of Al, fine Al8Mn5 phase increases in the microstructure of the experimental alloy, and the number of the second phase increases. Dynamic recrystallization occurred in all the experimental alloys during extrusion deformation, the grain size of Al alloy is significantly smaller than that of ZM60 alloy, and the average grain size of ZAM610 alloy is the smallest, which is 5.6µm. ZAM610 alloy has the best mechanical properties, with tensile strength, yield strength, elongation after fracture, U-notch impact work and non-notch impact work of 302.7MPa, 216MPa, 19.7%, 10.0 J/cm2 and 56.0 J/cm2, respectively. The fracture of the impact sample shows that there are many tearing edges in the ZM60 alloy, which shows the characteristics of quasi-cleavage fracture. The ZAM600 and ZAM610 alloys have a large number of dimples, which are characterized by dimple fracture. The improved properties of magnesium alloys after microalloying can be attributed to the formation of fine Al8Mn5 phase, which has good Zener blocking effect, refines the dynamic recrystallized grains, and improves the strength and impact toughness of the alloy.

“…As an advanced near-net forming technology, squeeze casting (SC) is one of the preferred processes for producing highperformance aluminum alloy parts, which has the advantages of simple and easy casting process, low cost, reliable and highquality forging products. [1,2] Squeeze casting technology is a technological method to obtain castings by applying high mechanical pressure on liquid metal poured into the mold cavity and making it form and solidify. [3] The squeeze casting technology can be divided into direct squeeze casting and indirect squeeze casting.…”

In order to optimize the process of indirect squeeze casting, computer aided engineering (CAE) technology was used to predict casting defects. Taking an adapter ring casting as an example, its 3D-model was established and its casting process was designed. The results indicate that, for indirect squeeze casting, when the liquid metal injects to mold cavity by casting system, temperature of liquid metal has dropped and started to solidify. At the same time, the runner has begun to solidify. If the cross-section of runner is too small, the runner pressure has not passed the casting to produce the effect of feeding, therefore this problem will lead to casting defects such as shrinkage cavity. As a result, full consideration should be given to the feeding effect of the runner in mold design. Simulation software can be used to simulate the temperature field of casting filling and solidification to design the runner reasonably.
