Paper Title:
Fe-Cr-Mn-(Co) High Damping Stainless Alloy (HIDAS)
  Abstract

Based on the recent requirements, high strength, high damping stainless alloy HIDAS was developed. The chemical compositions are Fe-12%Cr-22%Mn and Fe-12%Cr-22%Mn-2%Co. After solution annealing, microstructure consisting of austenite fcc , martensite hcp  and bcc ’. When cold work was given,  and  increased. Damping capacity increased with the increase of  phase. The mechanism of high damping capacity would come from the hysteretic motion of Shockley partial dislocations which are lying at interphase interface of /. This alloy has also high strength. This is due to fine structure of /. Because of these properties, HIDAS can be applied to machinery industries.
