Latest Patents

Jun-Dong Kim holds a patent for a method of manufacturing a Fe-Mn group vibration damping alloy. This alloy features a mixed structure of martensite and austenite, which is crucial for its damping properties. The alloy is primarily iron-based, with 14-22% by weight of manganese added. The manufacturing process involves mixing electrolytic iron and manganese in a molten state, casting the mixture as an ingot, and subjecting it to a series of heat treatments. The ingot is homogenized at temperatures between 1000°C and 1300°C for 20-40 hours, followed by hot rolling at 900°C to 1100°C for 20 to 90 minutes. Finally, the ingot is cooled using air or water.
