中文摘要：
半固态成形技术与传统成形技术相比，以其诸多的优点日益受到越来越多研究者的关注。在半固态成形技术的研究中，制备具有非枝晶组织的理想半固态浆料（坯料）是关键。将半固态浆料制备工艺分为两大类：液态金属半固态浆料制备和固态金属半固态坯料制备，并分别介绍了两类工艺中常用的几种工艺方法。电磁搅拌法和应变诱化激活法已有工业化应用；双螺旋搅拌法和半固态等温热处理法等比较有发展潜力；其他多种方法各有特点，可用于特定合金或者特定工作条件下的研究开发。
英文摘要：
Compared with the traditional forming technologies, semi-solid forming has so many advantages that attracts more and more researchers＇ attention as time goes on. The key issue of semi-solid forming is how to fabricate the proper slurry containing the non-dendritic microstructure. In this paper, the processes of fabricating semi-solid slurry are divided into two categories. One is from liquid metal, and the other is from solid metal. Several typical processes in both categories are summarized. The electromagnetic stirring process and the strain-induced melt activation process have been applied in the industrial practice. The twin-screw stirring process and the semi-solid isothermal heat-treatment process have more potential comparatively. Others also have different characteristics, and they may be developed to adapt to different alloys or different working conditions.
