摘要：
Controlling the microstructure of the Ti-35Nb-7Zr-5Ta alloy is fundamental for enhancing its strength and corrosion resistance in biomedical applications. This study examines how microstructural evolution through equal-channel angular pressing (ECAP) at room temperature and 300 degrees C influences Young's modulus, hardness, and corrosion resistance. ECAP refines grain size and promotes nanocrystalline beta-phase grains, alpha" phase decomposition, and omega phase precipitation. Room temperature ECAP decreases Young's modulus by reducing the beta-phase stability due to deformation, while 300 degrees C processing enhances hardness and Young's modulus due to finer microstructure and higher omega-phase fraction. Grain refinement accelerates passivation kinetics, enhancing corrosion resistance with a thicker and less defective passive film, especially at 300 degrees C, without significant changes in the elemental composition of the outer passive film.
