Title:
FE-CU ALLOY HAVING MESH STRUCTURE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2023/085532
Kind Code:
A1
Abstract:
An Fe-Cu alloy having a mesh structure and a method for manufacturing same are disclosed. The disclosed Fe-Cu alloy having a mesh structure comprises 65-85 atomic% of iron (Fe); and 15-35 atomic% of copper (Cu). In addition, the method for manufacturing an Fe-Cu alloy having a mesh structure formed by copper in an alloy structure comprises: a melting process of forming a molten metal by inputting iron and copper to a melting furnace and melting same so that the Fe-Cu alloy comprises 65-85 atomic% of iron and 15-35 atomic% of copper; a casting process of forming a casting by injecting the molten metal into a casting mold; a cooling process of naturally cooling the casting at room temperature; a heat treatment process of putting the naturally cooled casting into a heat treatment furnace and heat-treating same at a temperature of 945-980℃; and a quenching step of quenching the heat-treated casting in a cooling medium immediately after the heat treatment to rapidly cool same. According to the present invention, as the Fe-Cu alloy comprises copper (Cu) in an appropriate amount in iron (Fe) and has a mesh structure formed by copper (Cu) in the alloy structure, the Fe-Cu alloy has improved tensile strength and thermal conductivity while having high hardness.
