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

A eutectic Fe-15 wt.% Ti alloy was found to consist of a ferrite phase and ultrafine Fe2Ti lamellar phase. The ultrafine lamellar structure was discovered to be thermally stable at temperatures up to 600 °C. Furthermore, the alloy also exhibited a very high yield strength (780 MPa) at this temperatu...

Description
Summary:A eutectic Fe-15 wt.% Ti alloy was found to consist of a ferrite phase and ultrafine Fe2Ti lamellar phase. The ultrafine lamellar structure was discovered to be thermally stable at temperatures up to 600 °C. Furthermore, the alloy also exhibited a very high yield strength (780 MPa) at this temperature so that it can be considered as a potential engineering alloy for structural applications at this temperature regime. ► 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.
