This study conducts an in-depth exploration of the microstructure and mechanical properties of titanium alloy castings under normal temperature tensile conditions. By optimizing casting and stretching processes, significant improvements in the properties of titanium alloy castings were achieved. The specific work includes an analysis of the casting preparation process, observation of the microstructure, and characterization of the crystal structure. Mechanical property tests indicate that the titanium alloy castings, after process optimization, exhibit significant enhancements in both strength and ductility. Comparative analysis of the results reveals that the process parameters during preparation have a decisive impact on the microstructural characteristics and mechanical behavior. The relationship between microstructure and mechanical properties revealed in this study provides a theoretical foundation and process guidance for the application development of titanium alloy castings.
