Abstract: Methods of modeling metal alloys and forming those alloys are provided. The method involves comparing the strain accommodation and cleavage energies of a base alloy comprising a first metal and a chemical element different from the first metal. If a predetermined difference between those energies would be achieved, the base alloy will be sufficiently ductile. If that predetermined difference would not be achieved, the base alloy will not be sufficiently ductile, and the base alloy is modified (e.g., by adding a ductility component) until the predetermined difference in energies would be achieved, at which point, the alloy can be formed using conventional methods or further modified to achieve the desired degree of ductility.

Abstract: Provided is a method for producing alloy steel, the method comprising producing first alloy steel in a temperature holding furnace; maintaining the first alloy steel at a temperature of no lower than a melting point in the temperature holding furnace; and producing second alloy steel having an alloy content lower than the alloy content in the first alloy steel by melt mixing of the first alloy steel and molten steel. In the producing of the alloy steel, melting and storing of the ferroalloy are continuously performed, and thus, the temperature drop of the ferroalloy may be suppressed or prevented.
