Abstract

The paper reviews the current research status of titanium alloy 3D printing materials, explores the material properties of titanium alloys and their applications in aerospace, and analyzes in detail the microstructure non-uniformity caused by complex thermal history and cooling rate changes during the 3D printing process. This non-uniformity may have a significant impact on the overall performance of the material, especially in terms of tensile and fatigue properties. Subsequently, the influence of 3D printing technology on the microstructure of titanium alloys, including the control of printing parameters and microstructure characteristics, was analyzed in detail. The mechanical properties of titanium alloy 3D printing materials were studied, and the relationship between tensile and fatigue properties was explored. Finally, the effect of different heat treatments on material properties was analyzed, providing insights for titanium alloy 3D printing. The optimization design of alloy 3D printing materials provides a reference.
