| 中文摘要: |
| 随着轻量化需求的不断增加，镁合金作为最轻的结构金属材料受到了广泛关注。商用镁合金的强度与塑性仍然较低，限制了其在各领域的广泛应用，深入研究高性能镁合金板材制备工艺是打破其应用限制的关键所在。目前，轧制是生产高性能镁合金板材的重要手段，短流程、高效率、低成本的镁合金板材轧制工艺研发是国内外研究的焦点。综述了近几年先进轧制技术（如衬板控轧、非对称轧制、交叉轧制、叠轧、电脉冲辅助轧制及铸轧等）在制备高性能镁合金板材上的最新进展，浅析了几种新型轧制方法在工业应用方面的局限性，提出了未来高性能镁合金板材的研发需基于对工艺-组织-性能关系的深入探索，从新型低合金化体系开发和低成本短流程制备工艺两方面探索优化，为进一步满足镁合金工业应用需求提供思路。 |

| With the increasing demand for lightweight applications, as lightest structural metallic materials, magnesium alloys have been widely concerned. However, the strength and ductility of commercial magnesium alloys are still relatively low, limiting their wide applications. In-depth study on the preparation process of high performance magnesium alloy sheets is the key to broaden their applications. At present, rolling is an important preparation method for magnesium alloy sheets. Designing short-route rolling process with a high efficiency and low cost is the focus of researches at home and abroad. This paper summarized the latest progress in preparing high performance magnesium alloys by advanced rolling methods (such as hard-plate rolling, asymmetric rolling, cross rolling, accumulative roll bonding, pulsed electric current assisted rolling and twin-roll casting) in recent years. The limitations of several rolling processes in industrial application were figured out. It was pointed out that the preparation of high-performance magnesium alloy sheets in the future should be based on the in-depth exploration of relationship between process, microstructure and properties, and it should be optimized from two aspects: the new magnesium alloy system with low content of alloying elements and low-cost short preparation process. This provides a way of thinking for further meeting the industrial application requirements of magnesium alloys. |
