Purpose: in order to provide a Fe-Al-Mn alloy with high-intensitive and Highly-absorbing ability, it enters martensitic structure when it is applied to noise and vibration generating means by the transformation austenitic structure of the induction of Fe-Al-Mn alloys, when one manufacturing method of Fe-Al-Mn alloys, it is able to solve noise and vibration problem. Construction: manufacturing method is the following steps are included: one Fe-Al-Mn alloy of heat treatment has a chemical component comprising 0.01 to 0.The 0. of 1 weight % C, Si1 to 2.The 20. of 0 weight %, Mn0 to 40.0 weight %, 0.The 8. of 5 couples of AlThe 0. of 0 weight %, N01 to 0.The 0. of 3 weight % and Cr0 to 2.0 weight %, so that high-intensitive and Highly-absorbing ability realizes that wherein Fe-Al-Mn alloys obtain high-intensitive and Highly-absorbing ability and for example go ahead by acting in -196 to 150 deg. by the crystal boundary that different specific regions is coveredFe-Al-Mn alloys in the temperature range of C, thus convert austenitic structure enter and ' martensitic structure and wherein Fe-Al-Mn alloys obtain high-intensitive, done work by the Highly-absorbing ability of subzero processing work for example in -196 to 150 deg.C.Temperature range in 25 to -273 deg. that go ahead after Fe-Al-Mn alloysFe-Al-Mn alloys are executed in the temperature range of C
