主 题:NiTiNb shape memory alloy mechanical properties damping capacity
摘 要:The shape memory alloys are well known to exhibit high damping capacity in martensite state,but possess low yield strength because of the reorientation or de-twining of the martensite *** high damping mechanism of shape memory alloys was *** NiTiNb alloys with high yield strength and high damping capacity were designed and *** microstructure evolution,martensitic transformation behavior,damping capacity and mechanical properties of series NiTiNb alloys were *** view of the microstructure characteristics of the NiTiNb in-situ composites,the mechanism associated with high damping capacity and high yield strength was *** results show that NiTiNb alloys feature in in-situ composite,composed of primary NiTi(Nb) phase and fine lamellar eutectics of NiTi(Nb) andβ-Nb.
