铝合金和镁合金的半固态成形技术因其低成本、短流程、低能耗等优点被认为是一种加工性能优良的复杂零部件的先进成形方法.在过去的十年里,对半固态成形技术的工艺、显微组织与成形件性能的理解已取得较大的进展.本文首先回顾常见的半固态浆料制备方法,然后分析半固态成形铝合金与镁合金的性能和增强机制.随后,对半固态浆料显微组织演化和流变行为的主流观点进行分析.此外,还介绍半固态成形技术在我国的发展概况及近年来的部分应用实例.最后,对我国铝合金和镁合金的半固态成形技术中亟待解决的关键问题和未来的发展前景进行讨论.“,”Owing to its low cost, short process and low energy consumption, semi-solid processing (SSP) of aluminum (Al) and magnesium (Mg) alloys has been considered as a competitive approach to fabricate complicated components with excellent performance. Over the past decade, significant progress has been achieved in deeply understanding the SSP process, the microstructure and performance of the fabricated components in China. This paper starts with a retrospective overview of some common slurry preparation methods, followed by presenting the performance and the underlying mechanisms of SSP fabricated alloys. Then, the mainstream opinions on the microstructure evolution and rheological flow behavior of semi-solid slurry are discussed. Subsequently, the general situation and some recent examples of industrial applications of SSP are presented. Finally, special attention is paid to the unresolved issues and the future directions in SSP of Al and Mg alloys in China.
