Identification and Treatment of Academic Misconduct
To protect the rights of readers and authors and to maintain the quality and reputation of Journal of Plasticity Engineering, the paper will be rejected and treated accordingly if it is identified as academic misconduct after strictly testing and screening in the process of publication. The specific testing and identifying process and treatment methods are as follows:
Current research status of influencing factors of differences in metal electroplastic behavior
CAO Shou-zhen;GUO Sheng-hui;KANG Meng-qing;ZHANG Meng-fei;WEI Jun-xin;ZHANG Xin-long;WANG Tao;HAN Jian-chao;First, the current research landscape of metal electroplasticity from a statistical perspective was examined, the publication volume, geographical distribution, institutions and keywords of studies from 2010 to 2024 were analyzed, thereby identifying recent research hotspots and advancements in this field. Subsequently, the electroplastic behaviors and divergent characteristics of metals were comprehensively summarized based on electro-treatment input parameters and material-specific response properties. The mechanisms of thermal effects, electron wind effects and paramagnetic unpinning effects at microscopic and atomic scales were systematically elucidated to provide guidance for the research and application of electric-assisted forming technologies. Furthermore, existing approaches for decoupling non-thermal effects were critically reviewed from the perspective of experimental design, the first-principles calculations and simulation modeling, highlighting their respective strengths and limitations. Special emphasis was placed on the electroplastic deformation behaviors of materials with distinct crystal structures, focusing on resistivity, stacking fault energy and element diffusion. Finally, the challenges and future prospects in electroplasticity research were summarized to propose potential directions for further investigation.
Research progress of B2 precipitated phase in Fe-Mn-Al-C series low-density steel
YE Gui-yan;LIU Zhi;ZHANG Xiao-feng;LIU Yang;YANG Yong;Driven by the trend of lightweight of steel for automobile, Fe-Mn-Al-C series low-density steel has become a potential material that attracts much attention due to its low density and high strength and toughness. However, the properties of low-density steel are significantly influenced by B2 intermetallic compounds in the microstructure. In order to deeply reveal the formation rule and strengthening and toughening mechanism of B2 precipitated phase in Fe-Mn-Al-C low-density steel, in recent years, researchers at home and abroad have conducted systematic studies from multiple aspects such as alloy composition design, key element ratios and heat treatment process parameters. They have found that the performance of steel can be improved by regulating the morphology, distribution and size of the B2 phase. This paper systematically reviews the formation mechanism and strengthening effect of B2 intermetallic compounds in Fe-Mn-Al-C series low-density steels, focusing on composition-process-microstructure-properties. It mainly includes the synergistic effect of alloying elements, heat treatment assistance regulation, κ-carbide interaction, strengthening mechanism and special applications.
Research and application of optimization method of drawing bar based on response surface method
HUANG Zhen-yuan;ZHANG Zhi-hua;FANG Wei;LI Bing-hua;WU Yu-an;WU Ting-hao;To improve the stamping forming quality of automotive sheet metal parts, taking a automobile wheel cover product as an example, the segmented drawing bar optimization method based on response surface method was investgated. By employing the Box-Behnken design(BBD) test method and numerical simulations experiment, a response surface model was constructed to characterize the forming fracture tendency and wrinkling tendency of the formed part using drawing bar resistance as the variable. Validation results demonstrate that both the test coefficient R2 and adjusted test coefficient R■ of the model are close to 1, indicating high accuracy of the established response surface model. The optimized drawing bar resistance derived from this model achieved remarkable forming quality in simulation verification: rupture risk areas are reduced to less than 0.01%, wrinkling risk areas to less than 0.02%, and insufficient draw areas to less than 0.01%. Based on the optimal resistance values, corresponding drawing bar geometric parameters were designed and implemented in trial production. The practical manufacturing results confirm that the product exhibits no defects such as wrinkles or rupture, fully meeting production requirements.
