Latest Patents

Man-Eob Lee holds a patent for an Fe-Mn vibration damping alloy steel and a method for making the same. This alloy steel features a mixture structure of .epsilon., .alpha.', and .gamma.. The composition includes iron and manganese in quantities ranging from 10% to 24% by weight, along with limited amounts of impurities. The manufacturing process involves preparing an ingot at temperatures between 1000°C to 1300°C for 12 to 40 hours to ensure homogenization. Following this, the ingot is hot-rolled to produce a rolled alloy bar or plate. The alloy steel undergoes solid solution treatment at temperatures of 900°C to 1100°C for 30 to 60 minutes, followed by cooling through air or water. Finally, cold rolling is performed at a reduction rate greater than 0% and below 30% at around room temperature.
