“…However, the poor corrosion and wear resistance limits its further application. In contrast, aluminum alloys exhibit excellent corrosion resistance and good mechanical properties [4,5]. Therefore, the layered composites of magnesium and aluminum alloys are promising structural materials, due to combining the advantages of the two metallic materials and giving the opportunity to provide the unique functional and operational properties of the layered materials [6].…”

In this work, an improved explosive welding technique was investigated to fabricate a thin Mg/Al plate, where an additional thin aluminum sheet was used as a buffer layer between the explosive and the Al plate, and the Mg plate was rigidly constrained by a steel plate to avoid excessive deformation. Moreover, the welding parameters were optimized using theoretical analysis and numerical simulation, and the interfacial behavior was simulated using the SPH method. The bonding properties of the achieved joints were investigated using microstructure observation and mechanical tests. It was concluded that this technique is an effective method for producing a thin Mg/Al composite plate. In both morphology observation and mechanical tests, an excellent bonding quality was confirmed. In addition, smoothed particle hydrodynamics (SPH) simulation revealed an extreme condition of local high temperature and plastic strain in the welding process, and the characteristic parameters of waves obtained using simulation are well congruous with the experiment.

In strip rolling, hydraulic automatic gauge control (HAGC) system is the key element to guarantee the precision of strip gauge. The stability of the kernel pressure closed loop (PCL) in the HAGC system plays an essential role in guaranteeing the rolling process with high performance. Nevertheless, there is some difficulty in exploring the instability mechanism of the HAGC system due to the fact that the PCL is a representative nonlinear closed-loop control system. In this work, for each component of the HAGC system, the mathematical model was established. And on the basis of the linking relation of various elements, we derived the incremental transfer model of the PCL system. Furthermore, in accordance with the deduced information transfer relation, the transfer block diagram of disturbing variable of the PCL system was obtained. Moreover, for the purpose of deriving the instability condition of the PCL system, the Popov frequency criterion was employed. The instability conditions of the HAGC system were obtained under PCL control. Furthermore, the derived instability conditions of the HAGC system were experimentally verified under various working conditions. The research results provide a fundamental foundation for studying the instability mechanism of the HAGC system.

As one of the main methods to solve deformation mechanics, the principal stress method (PSM) is widely used in stress analysis and technology optimization of metal forming processes. The stress assumption, yield criterion and boundary conditions have been investigated according to the frequently asked questions in teaching and application of the PSM, and then the determination rule was proposed and described. The yield criterion, boundary conditions and calculated results should keep the corresponding relationship with the initial stress assumption of the micro-element. The stress distribution and load in the plane deformation of the rectangular workpiece was successfully solved using the PSM based on the rule proposed and FEM. The average relative error is 8.3% between the predicted loads by FEM and PSM, and the stress and load predicted by PSM are in good agreement with the FEM. Furthermore, the same calculated results of stress were obtained under different conditions, indicating that the rule proposed is reliable and practical significance for and application of the PSM.
