WebThe damping capacities of Fe-Mn binary alloys have been investigated in a wide range of manganese content from 5 to 30 wt%. The damping capacity increases with increasing manganese content, attains a maximum at approximately 17 wt% Mn, and decreases with further manganese content. It is suggested that the damping mechanisms of Fe-Mn … WebJun 17, 2024 · The yield strength of the current HEAs (1138 and 1362 MPa for the O-2 and N-2 HEAs, respectively.) is much higher than that of the traditional high-damping alloys (~200 to 600 MPa) and twice that of the Ti-25Nb-1.5O Snoek-type high-damping alloy (~665 MPa). The here designed HEAs also have large tensile ductility (~20%).
