A novel eutectic Fe-15Â wt.% Ti alloy with an ultrafine lamellar structure for high temperature applications

► A eutectic Fe-15 wt.% Ti alloy presents a fine lamellar structure (ferrite + Fe2Ti). ► Both inter-lamellar spacing and Fe2Ti lamella thickness are smaller than 1 μm. ► Its yield stress at 600 °C is as high as 780 MPa.
