• Fe-6.5 wt%Si alloy
• Columnar grain
• Deformation rate sensitivity

Outstanding ductility of Fe-6.5 wt%Si alloy can be obtained in a wide deformation rate range (1-125 x 10(-4) s(-1))due to the ultra-low deformation rate sensitivity of the columnar-grained alloy with (100) orientation deformed at 400 degrees C. This finding provides a high-efficiency approach to prepare Fe-6.5 wt%Si alloy and a guideline for microstructure control.
