半固态金属加工是一项广为人知的技术，可在广泛的行业中用于提高制造产品的质量。该技术将合金的触变性能控制在其固相线和液相线温度范围内。一般来说，大多数已知的合金在高固相分数时可以形成半固态浆体，其余合金在低固相分数时可以形成浆体。这为许多金属和合金在今天的铸造工业中被加工成半固态浆料提供了机会。然而，只有少数研究人员研究了这项技术可能用于一种新的基于金属的添加剂制造或3D打印工艺。本文综述了从触变流变学、半固态金属加工方法到触变金属3D打印的文献和研究成果。调查表明，未来还需要进行更多的工作，包括触变金属流动力学的研究，半固态金属挤压的建模和仿真，以及进一步开发全触变3D打印系统。
ABSTRACT Semisolid metal processing is a well-known technology that can be used to enhance manufacturing product quality in broad industries. The technology controls the thixotropic properties of alloys within their solidus and liquidus temperature ranges. In general, most known alloys can generate semisolid slurries at high solid fractions, and the remaining can form slurries at low solid fractions. This has provided opportunities for many metals and alloys to be processed as semisolid slurries in today’s casting industry. However, only a few researchers studied this technology potentially for a new metal-based additive manufacturing or 3D printing process. This article reviewed literature and findings from thixotropy rheology and semisolid metal processing methods, finally to thixotropic metal 3D printing. The survey shows that more future work is needed, including the investigation of thixotropic metal flow mechanics, the modelling and simulation of semisolid metal extrusion and further development of a fully thixotropic 3D printing system.
