Conclusions
A correlation was established between the content of ɛ-phase in the structure of the alloy Fe-Mn and its vibration absorbing properties. An increase of the amount of ɛ-martensite to 50–60% leads to an improvement of the vibration absorbing properties; when the content of ɛ-phase is further increased, the vibration absorbing properties deteriorate. To ensure maximal vibration absorption, the alloy has to contain 50–60% ɛ-phase. It was also cleared up what effect some heat treatment parameters have on the amount of ɛ-phase contained in the alloy.
