摘要： An Fe-Mn vibration damping alloy steel having a mixture structure of .epsilon., .alpha.' and .gamma.. The alloy steel consists of iron, manganese from 10 to 24% by weight and limited amounts of impurities. The alloy steel is manufactured by preparing an ingot at a temperature of 1000.degree. C. to 1300.degree. C. for 12 to 40 hours to homogenize the ingot and hot-rolling the homogenized ingot to produce a rolled alloy bar or plate, performing solid solution treatment on the alloy steel at 900.degree. C. to 1100.degree. C. for 30 to 60 minutes, cooling the alloy steel by air or water, and cold rolling the alloy steel at a reduction rate of greater than 0% and below 30% at around room temperature.
