Special Issue Information

Dear Colleagues,

Metallic materials are widely used in the aerospace, transportation, and petrochemical industries. On the one hand, advanced plastic forming processes, such as hot stamping, extrusion forming, and forging forming, help to prepare high-performance parts with complex shapes. On the other hand, advanced severe plastic deformation processes, such as equal channel angular extrusion, high pressure torsion, multi-directional forging, and cumulative rolling welding, can greatly improve the microstructure and mechanical properties of metal materials. The goal of this Special Issue is to publish original, important, and developed research papers that focus on metal plastic deformation and forming.

In this Special Issue, we welcome the latest research on metal plastic deformation and forming. Appropriate topics include but are not limited to the following: metal material stamping, forging, extrusion, bending, or torsion forming process and finite element simulation technology; the severe plastic deformation process of metal materials; and the microstructure evolution, mechanical properties test, and related simulation during plastic deformation.

In this study, the constitutive equation of the high-strength Mg-Gd-Y-Zn-Zr alloy sheet was established by tensile tests at different temperatures and different tensile rates. The U-shape bending forming process of the sheet was simulated under different process conditions by the DEFORM software. The variation rules of the stress field, strain field and free bending force of the formed parts were analyzed, and the accuracy of the finite element simulation was verified by the U-shaped bending test. Studies have shown that the equivalent stress, equivalent strain and free bending force decreased with the increase in forming temperature. With an increase in the stamping speed, the equivalent stress and free bending force increased, while the equivalent strain did not change significantly. Notably, the maximum difference in the free bending force between the test and simulation was less than 10%. The results of this study can provide guidance for the stamping forming of high-strength Mg-Gd-Y-Zn-Zr alloy sheets. Full article

This study aims to enhance the efficiency of pickling processes by investigating the impact of strip speed and acid flow rate on the turbulence of the acid solution within the pickling tank. The research quantitatively evaluates the flow field state and distribution of acid temperature within the pickling tank. Through finite element simulation, factors such as jet velocity, strip motion velocity, and acid temperature are considered to determine the turbulence intensity, turbulent kinetic energy, convective heat transfer coefficient, and average temperature of the near-wall layer of the strip surface under the oblique jet. This analysis considers the effects of these parameters on the flow field within the pickling tank. Furthermore, simulations are conducted to assess the turbulence intensity of the acid solution under various conditions. The study reveals that the intake flow rate has a substantial influence on turbulence and temperature rise at the strip exit and inlet, albeit less so, within the acid tank itself. However, an increase in strip speed notably impacts the turbulence within the center of the acid tank. These findings are invaluable for regulating the pickling process and maintaining optimal strip surface quality in industrial production settings. Full article
