“…The formation mechanism and control methods of grain morphology and size in the reaction layer still need further extensive investigation. Nie et al (Nie et al, 2019) have investigated the orientation relationship between the IMCs and the matrix using EBSD and layer may be referred to as the high nucleation energy of the Al3Mg2 phase and may disappear when the intermetallic compound development is significantly enhanced by the governing kinetics (Song et al, 2022;Zhu et al, 2020). Furthermore, Fig.…”

Against the background of the lightweight industry, the development of new aluminum alloys with high specific strength and low production cost is one of the main goals in modern industry. However, hot tearing is one of the most serious and irreparable defects in the production of thin-wall, complex and large castings of aluminum alloy, which limits the application of aluminum alloys [1][2][3] . Hot tearing is mainly attributed to insufficient feeding during solidification and the large-size thermal stress and strain at the end of solidification [4] . The fracture morphology shows that hot tearing usually occurs in the intergranular area, and the residual liquid or separated solid dendrite bridge is observed at the crack [4][5][6] .

“…Different processes, such as rolling [ 9 , 10 ], friction stir-welding [ 11 , 12 ], extrusion [ 13 , 14 ], and compound casting [ 15 , 16 , 17 ], could be used to prepare Al/Mg bimetal. Among them, it is noteworthy that compound casting is suitable for fabricating Al/Mg bimetal objects with complex shapes and large sizes.…”

In this work, ultrasonic vibration treatment (UVT) was introduced to improve the interfacial microstructure and bonding strength of A356/AZ91D bimetal processed via lost foam compound casting (LFCC). The interfacial microstructure and mechanical properties of the Al/Mg bimetal processed via LFCC with different UVT durations were investigated. Results revealed the UVT did not change the composition of phases at the interface. The Al/Mg bimetallic interface consisted of an intermetallic compound area (β-Al3Mg2 + γ-Al12Mg17 + Mg2Si) and eutectic area (δ-Mg + γ-Al12Mg17 + Mg2Si). When the duration of the UVT was increased, the gathered Mg2Si particles at the intermetallic compound area were refined to sizes of no more than 5 μm and became more homogeneously dispersed in the intermetallic compound area and diffused in the eutectic area, which could be attributed to the removal of oxide film and the acoustic cavitation and streaming flow effects induced by the UVT. The microhardness of the Al/Mg bimetallic interface was not obviously changed by the increase in UVT duration. The shear strength of the Al/Mg bimetal was increased with UVT and reached maximum with a UVT duration of 5 s, with a value of 56.7 MPa, which was increased by 70.3%, compared with Al/Mg bimetal without UVT. This could be attributed to the removal of the oxide film at the Al/Mg bimetallic interface, which improved the metallurgical bonding of the Al/Mg interface. Additionally, the refined and homogeneously dispersed Mg2Si particles played an important role in suppressing the propagation of cracks and enhancing the shear strength of the Al/Mg bimetal.
