Method for producing magnetic material using melt-spinning process
The patent US12033794B2 outlines a method for producing magnetic materials through a series of precise steps aimed at achieving a high-quality final product. The process begins with the provision of a mixture of alloys, which is then melted to create a molten mixture. This molten alloy undergoes a melt-spinning process within a controlled chamber, where it is rapidly solidified using a rotatable wheel, resulting in a preliminary metallic ribbon. The method emphasizes the importance of grain size refinement and uniformity, achieved by delivering a coolant to both the top and bottom sides of the ribbon. This cooling process is critical for maintaining consistent internal pressure and temperature conditions within the chamber, which are essential for the desired material properties.
The claims further specify that the coolant may include noble gases in liquid form, such as liquid argon or helium, and detail the target grain sizes for the final metallic ribbon, with averages less than 45 nm for the central portions. The method also stipulates that the differences in grain size between the central and edge portions of the ribbon should be minimal, ensuring uniformity across the material. Additionally, the mixture of alloys is defined to include rare earth elements and other specified metals, enhancing the magnetic properties of the final product. Overall, the patent presents a comprehensive approach to producing advanced magnetic materials with controlled microstructural characteristics, which could have significant applications in various technological fields.
