Abstract
The effect of carbon addition on the microstructure and mechanical properties of Fe-Zr and Fe-Zr-Nb ultrafine eutectic-dendrite composites has been investigated. Addition of carbon leads to the formation of iron solid solution strengthened by carbon interstitials and carbide particles encapsulated by ar-Fe dendrites preferentially nucleated on the carbides. Consequently, the ultrafine eutectic Fe-5Zr-5Nb-0.3C (mass%) alloy exhibits high compressive strength (∼ 1.2 GPa) and large plastic strain (∼24%). The present study suggests another effective way to enhance the mechanical properties of Fe-based nano-eutectic alloys.
