“…Compound casting is defined as the pouring of a metallic melt into/around another metallic solid part and the formation of a continuous interface between the two metallic parts [14,19,20] . The advantages of compound casting include low production costs, low energy consumption, and a simple production procedure that outweigh its disadvantages [21] . Despite these advantages, bonding metals such as Al/Mg by compound casting has disadvantages, including the formation of defects, such as an unbounded zone, gas porosity or shrinkage at the interface, oxide layers on the surface, and precipitation of brittle intermetallic compounds with a high hardness such as Al 12 Mg 7 and Al 3 Mg 2 [6,15,20] .…”

IntroductionMagnesium (Mg), with a density of two-thirds of aluminum (Al), is one of the light metals. Al has high specific strength, good formability, high corrosion resistance, and superior recycling potential [1][2][3][4] . Mg has good machinability, castability, and high damping capacity [3] . Due to these properties, Mg and Al have enormous potential for use in the automotive, aerospace, and marine industries [5,6] . The bonding of Mg and Al would combine their excellent properties, including a low density and high specific strength [7] . Several joining methods have been reported to fabricate Al-Mg bimetallic structures using accumulative roll bonding (ARB) [8] , conventional fusion processes [6] such as tungsten arc welding [9] , laser beam welding (LBW)

“…Therefore, fracturing process of rock is affected by coupled stress chemical solutions. 24 Unlike common fluid-solid interaction problems, the whole computational domain of fluid-solid interaction in porous materials can be divided into three regions: the pure fluid region, the porous material region, and the pure solid region. Porous material region is shared by the fluid and solid models with all fluid solution variables and displacements.…”

Deformation of underground rocks, also named rock creep, is treated as porous materials which usually results in many engineering problems, especially in petroleum engineering. However, it can be controlled by fluid-solid interaction in porous materials, and the deformation mechanism of underground rocks with fluid-solid interaction was analysed by finite element computing method. Specifically, an Iterative computing method and a computational procedure of two-way fluid-solid coupling are used to simulate deformation process until the fluid and solid solution variables are fully coupled. A typical application example was taken in Jinzhou oil production plant of Liaohe Oil Field Company, and a finite element model is built by combined application of parasolid and native modelling methods. According to the calculation results, deformation mechanism of underground rocks is proposed, and some advice is also presented.

“…Al has better solidification characteristics when compared to other cast metals such as copper alloys [24]. Casting is one of the low cost fabrication techniques for fabricating Al metal components and caters to 98% of structural applications of Al [15,25]. Solid-liquid compound casting has been effectively used to develop hybrid composite wherein liquid metal is poured on solid metal.…”

“…These studies largely reported the metallurgical, mechanical, and tribological properties of the systems. Song et al [25] fabricated Al/Mg compound materials by a solid-liquid bonding method and good bonding between the two matrices were observed with the interface layer primarily consisting of Al 12 Mg 17 and Al 3 Mg 2 . Hajjari et al [29] used compound casting to join aluminium to magnesium.…”

In this study, hybrid composite consisting of aluminium (Al) shell and magnesium/glass microballoon (Mg-20 wt.% GMB) syntactic composite core was fabricated in a shell-core pattern by combining powder metallurgy and disintegrated melt deposition (DMD) techniques. Physical, microstructural and mechanical properties of as-cast Al and Al/Mg-20GMB hybrid composite were examined. Approximately 13% reduction in density (with respect to aluminium) was realized through the use of a syntactic composite core. Microstructural investigations revealed reasonable interfacial integrity between aluminium shell and Mg-GMB core material and the presence of Al, Mg and GMB phases. The interface region showed a hardness of 109 ± 2 Hv in comparison to the hardness of Al shell region (68 ± 4 Hv) and Mg-20GMB core region (174 ± 5 Hv). In comparison to as-cast Al, the yield strength and ultimate compressive strength of the as-cast Al/Mg-20GMB hybrid composite increased by ~65.4% and ~60%, respectively. Further, the energy absorption under compressive loading for the Al/Mg-20GMB hybrid composite was ~26% higher compared to pure Al. This study validated that Al/Mg-20GMB hybrid composite with superior absolute and specific mechanical properties can be fabricated and used for weight critical applications.
