Special Issue Information

Dear Colleagues,

Currently, new forming processes are constantly emerging, and modeling/simulation plays an important role in the research into metal forming. In-depth research into the deformation mechanism, microstructure evolution, stress and strain, shape, defects, damage, and fracturing during metal forming is needed through experimental or multi-scale modeling/simulation. The goal of this Special Issue is to publish original, important, and well-developed research papers that focus on modeling/simulation and experiments in metal forming.

In this Special Issue, we welcome the latest research on metal forming. Appropriate topics include but are not limited to the following: sheet metal forming, forging, extrusion, drawing, rolling, or special forming processes and numerical simulations (the finite element method, cellular automaton, the phase field method, etc.); microstructure evolution and control; constitutive behavior; the mechanical properties of deformed materials; and the optimization of process conditions.

The exploration of the relationship between process parameters and grain evolution during the thermal deformation of rare-earth magnesium alloys using simulation software has significant implications for enhancing research and development efficiency and advancing the large-scale engineering application of high-performance rare-earth magnesium alloys. Through single-pass hot compression experiments, this study obtained high-temperature flow stress curves for rare-earth magnesium alloys, analyzing the variation patterns of these curves and the softening mechanism of the materials. Drawing on physical metallurgical theories, such as the evolution of dislocation density during dynamic recrystallization, recrystallization nucleation, and grain growth, the authors of this paper establish a cellular automaton model to simulate the dynamic recrystallization process by tracking the sole internal variable—the evolution of dislocation density within cells. This model was developed through the secondary development of the DEFORM-3D finite element software. The results indicate that the model established in this study accurately simulates the evolution process of grain growth during heat treatment and the dynamic recrystallization microstructure during the thermal deformation of rare-earth magnesium alloys. The simulated results align well with relevant theories and metallographic experimental results, enabling the simulation of the dynamic recrystallization microstructure and grain size prediction during the deformation process of rare-earth magnesium alloys.
