摘要
边部裂纹严重影响镁合金板材在轧制生产中的成形性能,是镁合金轧制不可忽视的缺陷。精确的损伤分析有助于揭示边部裂纹的产生机制,因此需要对镁合金轧制边裂损伤模型进行研究。尽管目前镁合金轧制边裂损伤分析模型的研究取得了一定的进展,但总结现有数据的综述论文较少。本文从镁合金轧制边裂损伤机制出发,分析了国内外学者关于边裂损伤的定义、形成、影响因素和控制的研究进展,重点汇总了非耦合与耦合的镁合金轧制边裂损伤分析模型,为完善镁合金轧制工艺理论体系和改进镁合金轧制工艺提供了参考,最后指出了当前镁合金轧制边裂损伤研究中存在的问题,并对未来的研究方向进行了展望。
The edge cracks seriously affect the formability of magnesium alloy sheet in rolling production,and can not be ignored in magnesium alloy rol-ling.It is necessary to study the generation mechanism and damage model of magnesium alloy rolling edge crack to achieve accurate da-mage analysis of edge crack.Although there are many researches have been published on the analysis model of magnesium alloy edge crack damage,there are few papers summarizing the available data.In this summary,the mechanism of edge crack damage in magnesium alloy rolling is briefly described.The research progress of the definition and formation,the influencing factors,the damage control of edge crack damage are analyzed.The analysis models of magnesium alloy rolling edge crack damage based on continuum damage mechanics,continuous damage mechanics and mesoscopic damage mechanics are summarized,which provides reference for improving the theoretical system of magnesium alloy rolling process and improving the rolling process of magnesium alloy.Finally,the existing problems in the research of edge crack damage of magnesium alloy rolling are pointed out,and the future research direction is prospected.
