Research progress on the bending performance regulation strategies of magnesium alloy under the dominance of microstructure, processing, and simulation
摘要
The application breadth and strategic value of magnesium alloy bending parts, which offer significant lightweight advantages within the manufacturing field, continue to increase. However, forming defects such as cracking and springback that are generated during the bending process, along with the problem of accurate statistics of dynamic response data of overall macro and micro characteristics, seriously restrict the improvement of bending performance and hinder its application toward lightweight and depth. The three key strategies based on microstructure dominance, process path dominance, and numerical simulation dominance have become the core means to improve the bending performance due to the significant effectiveness of their control effects. This paper systematically reviews the latest progress in the regulation of bending properties of magnesium alloys, with a focus on the diversified design of microstructure, multifaceted innovation of process path, and numerical simulation of bending properties. Furthermore, challenges and future development directions of the research are prospected, in order to provide a reference for the theoretical innovation and industrial implementation of the bending performance control strategy of magnesium alloys.
