1. A method comprising:
a. supplying a metal alloy comprising Fe at a level of 61.0 to 88.0 atomic percent, Si at a level of 0.5 to 9.0 atomic percent, Mn at a level of 0.90 to 19.0 atomic percent and optionally B at a level of up to 3.0 atomic percent; b. melting said alloy and cooling and solidifying and forming an alloy having a thickness of greater than or equal to 20 mm and up to 500 mm and a yield strength of 300 MPa to 600 MPa
wherein said solidified alloy has a melting point (Tm) and heating said alloy to a temperature of 700° C. to below said alloy Tm at a strain rate of 10−6 to 104 and reducing said thickness of said alloy and providing a first resulting alloy having a yield strength of 200 MPa to 1000 MPa and stressing said first resulting alloy and providing a second resulting alloy that has a thickness of 0.1 mm to 25.0 mm and indicates a tensile strength of 400 MPa to 1825 MPa and elongation of 2.4% to 78.1%. |
