Ultrahigh strength and large plasticity of nanostructured Ti62Nb12.2Fe13.6Co6.4Al5.8 alloy obtained by selectively controlled micrometer-sized phases

• Nanostructured Ti62Nb12.2Fe13.6Co6.4Al5.8 alloy with excellent mechanical property was fabricated.
• Deformation mechanism of the nanostructured alloy with different micron-sized phases is proposed.
• Micron sized phases during deformation play a key role on work-hardening behavior.
