AZ31/Mg‐Y/AZ31 composites are fabricated by hot rolling bonding. To identify the formation mechanism of the microstructure in the interface adjacent region, additional hot rolling or/and diffusion annealing are also conducted on the base of the initial AZ31/Mg‐Y/AZ31 composite. Scanning electron microscopy, energy dispersive spectroscopy, and electron backscatter diffraction are used to characterize the microstructures and chemical compositional distributions. Vicker's microhardness tests are conducted to determine the local mechanical property. It is found that in the Mg–Y layer of the AZ31/Mg‐Y/AZ31 composite, the grain size in the interface‐adjacent region is much finer than that in the central part. Much finer Al2Y particles compared with those in the traditional Mg–Al–Y alloys are formed in the interface‐adjacent region. The formation of the fine grain in the interface‐adjacent region may be mainly related to the Al2Y particles rather than the accommodation deformation between layers. Both the grain refinement and the formation of Al2Y particles contribute to strengthening of the Mg–Y layer. The results in this work may provide a novel method to prepare fine and dispersed high‐melting‐point particles in Mg alloys, thus leading to strong and high‐thermal‐stability Mg alloys.

“…Therefore, after two-pass rolling, the texture of the workpiece is much weaker than that of the traditional rolling process. Sun et al 43) and Chen et al 44) used similar methods to fabricate AZ31 alloy strips and Al/Ti/Al clad strips and obtained similar results. The third method is that the two rolls are cylinders, and one of the rolls is raised and pressed repeatedly to change the thickness of the roll gap.…”

Complex section products have significant lightweight and functional characteristics, and the twin-roll casting (TRC) is characterized by high efficiency and short flow. Hence, the TRC process for fabricating complex section products combines both advantages and will have a broader market demand and application prospect. In this paper, the research progress in recent years is reviewed, and novel TRC processes are divided into three categories according to the product section characteristics, namely transverse variable profiled strip, longitudinal variable profiled strip, and circular section products. The essence of the TRC process of complex section products is to change the steady-state characteristics in time series and the uniform characteristics in spatial distribution into transient or nonuniform. The technical principle, deformation characteristics, influence mechanism, are systematically analyzed. The current challenges and future directions of the TRC process are discussed.

“…The metallurgical bonding interface is crucial for laminate metal matrix composites, which determines their further manufacturing and application. [ 1,2 ] Traditionally, atom diffusion occurs across the cladding interface during the bonding process due to a chemical formula gradient, resulting in a composition transition zone at the cladding interface. [ 3 ] In the composition transition zone, atoms dissolve into the substrate or react with each other, which affects the mechanical properties of laminate metal matrix composites.…”

Interfacial Bonding Behavior of Stainless Steel/Carbon Steel–Laminated Composites Fabricated by Liquid–Solid Bonding

Liquid–solid (L–S) bonding is a promising technique for preparing laminate metal matrix composites, nevertheless, interfacial heat transfer and microstructure evolution are complicated and strongly affect the bonding behavior. Herein, stainless steel (SS)/carbon steel (CS)‐laminated composites are fabricated by L–S bonding method under different conditions. The interfacial heat‐transfer behavior and microstructure characteristics are investigated by simulations and experiments, and the bonding mechanism are analyzed. Dramatic heat transfer occurs at the cladding interface and results in a vertical temperature gradient, the substrate temperature sharply increases to the peak value and then decreases with reducing cooling rate. Metallurgical bonding cladding interfaces without oxides are obtained under a melt temperature of 1923 K and substrate‐preheating temperatures of 773 and 973 K. During the L–S bonding process, an Fe–O oxide layer covering the substrate forms and then spalls from the substrate due to cracking or decomposition due to intense heat flux during the heating stage. Subsequently, solid diffusion or dissolution diffusion initiates at the fresh surface and forms flat or waved cladding interface, and the diffusion distance of Cr is significantly improved by dissolution diffusion, resulting in strengthened cladding interface zone of the SS/CS‐laminated composite.
