摘要
镁合金作为一种“绿色轻质金属结构材料”,已成为实现轻量化、复杂化、个性化结构制造的必要选择。为满足高端装备对构件高性能的要求,打破传统制造技术的壁垒,柔性度高、清洁度高、精度高的激光制造技术逐渐被采用,以实现结构复杂化及个性化制造。其中,镁合金的激光切割、焊接、表面改性及增材制造是当前激光制造技术发展的主要方向。为此,分别阐述了不同激光制造技术的基本原理、研究焦点和相关研究进展,从材料、工艺、结构、机理等维度,对镁合金激光制造技术的发展进行了总结,并提出以“减形增性”为目标,实时监测等多尺度手段复合的展望。
As a “green and lightweight metallic structure material”, magnesium alloy has become a necessary choice to realize lightweight, complex and personalized structure manufacturing. In order to meet the requirements of high-end equipment on the high-performance components and break the barriers of traditional manufacturing technology,laser manufacturing technology of high flexibility, high cleanliness and high precision is gradually adopted to achieve complex and personalized structures. Thereinto, laser cutting, laser welding, laser surface modification and laser additive manufacturing of magnesium alloy are the currently main developing directions of laser manufacturing technology.Therefore, the basic principles, research focus and related research progress of different laser manufacturing technologies are introduced respectively. The development of laser manufacturing technology of magnesium alloy is summarized.Furthermore, multi-scale tools such as real-time monitoring are proposed with the goal of “reducing shape and increasing property”.
