摘　　要：钛合金具有密度低、比强度高、抗高温氧化能力强以及良好的耐腐蚀性能,在现代国防、航空航天、海洋船舶、化工设备等领域得到了广泛应用,尤其在航空航天工业领域,是重要的战略金属材料。装备制造领域的不断发展对钛合金铸件的性能要求越来越高,且钛合金铸件结构也呈现薄壁化、复杂化及精密化趋势。因此,发展新型的钛合金快速铸造技术成为关注热点。主要综述了钛合金传统砂型铸造技术现状以及基于3D打印的新型钛合金快速砂型铸造技术的工艺发展,并指出了存在的问题及其应用前景。Titanium alloy is widely used in modern national defense, aerospace, marine shipping, chemical equipment and other fields, due to the characteristics of low density, high specific strength, strong high-temperature oxidation resistance and desirable corrosion resistance, which is an important strategic metal material special in the aerospace industry.With the development of equipment manufacturing, the performance of titanium alloy castings is increased in demand, and the structure of titanium alloy castings tend to be thin-wall, complexity and precision.Therefore, the development of novel rapid casting technology for titanium alloy was focused. The status of traditional sand casting technology and development of novel rapid sand casting technology for titanium alloy based on 3D printing were reviewed, and the corresponding problems and application prospects were proposed.
