Abstract: | 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 variants.The high damping mechanism of shape memory alloys was introduced.The NiTiNb alloys with high yield strength and high damping capacity were designed and prepared.The microstructure evolution,martensitic transformation behavior,damping capacity and mechanical properties of series NiTiNb alloys were investigated.In view ... |
