| Zusammenfassung: | 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. |
