摘要

Titanium alloys are crucial in aerospace and medical industries due to their high strength-to-weight ratio, corrosion resistance, and high-temperature performance. Spinning, an efficient forming technique, offers high precision, reduced waste, and enhanced mechanical properties, despite challenges like hardness and temperature sensitivity. This review provides a comprehensive, synthesized overview of microstructural evolution in titanium alloy spinning. It analyzes fundamental principles, key process parameters (including rotational speed, axial force, preheating temperature, tool type, and coating material), and their profound influence on product quality. By synthesizing experimental and theoretical studies, this paper elucidates deformation mechanisms, examining how parameters and heat treatments drive microstructural changes including grain refinement, texture development, and phase transformations. Key insights show that precise control and strategic heat treatments are paramount for achieving homogeneous, ultrafine-grained microstructures and superior mechanical performance. Challenges, solutions, and crucial future research directions for advanced simulation and alloy design are outlined.
