Abstract: | The damping capacity mainly comes from the motion of martensite boundaries, which is larger than that from different phase interfaces in TiNi-based shape memory alloys. The fine and disperse precipitation in the TiNi matrix will increase the damping capacity of the TiNiNbMo alloy in the martensitic state but little affect the damping capacity during the martensite transformation. The dispersed Nb-rich particles and the internal stress fields around them influence the change tendency of damping capacity with the increasing of strain amplitude. |
