    Published 2025-03-01
    “…Room temperature ECAP decreases Young's modulus by reducing the β-phase stability due to deformation, while 300 °C processing enhances hardness and Young's modulus due to finer microstructure and higher ω-phase fraction. Grain refinement accelerates passivation kinetics, enhancing corrosion resistance with a thicker and less defective passive film, especially at 300 °C, without significant changes in the elemental composition of the outer passive film.…”
