“…It is known that the damping capacity of NiTi in martensitic state is practically independent of temperature [11,12]. However, the damping capacity of Ti 3 Sn is dependent on the change of temperature [8]. Thus, this high damping capacity of the composite at low temperatures can be ascribed to the contribution of the Ti 3 Sn component.…”

“…Recently, Ti 3 Sn intermetallic compound has been reported to exhibit exceptionally high damping capacity [8], raising high expectations for innovative applications. The maximum damping capacity of Ti 3 Sn has been reported to reach 0.2 (indexed by tan d) [8], which is over four times higher than those of typical commercial Mn-Cu-based high-damping alloys (with tan d of about 0.05) [9,10] and NiTi shape memory alloys (tan d approximate 0.04) [11,12].…”

However, due to the lack of adequate slip systems in its D0 19 crystal structure, the Ti 3 Sn intermetallic compound is extremely brittle [13,14].…”

a b s t r a c tThe concept of transformation-induced plasticity effect is introduced in this work to improve the plasticity of brittle intermetallic compound Ti 3 Sn, which is a potent high damping material. This concept is achieved in an in situ NiTi/Ti 3 Sn composite. The composite is composed of primary Ti 3 Sn phase and (NiTi + Ti 3 Sn) eutectic structure formed via hypereutectic solidification. The composite exhibits a high damping capacity of 0.075 (indexed by tan d), a high ultimate compressive strength of 1350 MPa, and a large plasticity of 27.5%. In situ synchrotron high-energy X-ray diffraction measurements revealed clear evidence of the stress-induced martensitic transformation (B2 ? B19 0 ) of the NiTi component during deformation. The strength of the composite mainly stems from the Ti 3 Sn, whereas the NiTi component is responsible for the excellent plasticity of the composite.

“…Vdovychenko et al 11 reported that the intermetallic compound Ti 3 Sn shows unusually strong mechanical damping from 1 to 200 Hz, and also from 20 to 100 kHz. At low frequencies, the damping remains high in the temperature range 125-473 K. 11 Although the damping mechanisms of Ti 3 Sn intermetallic compounds are still unknown, it has important application potential due to higher damping than the commercial Mn-Cu based damping alloys.…”

In this paper, ductile b-Ti was selected to toughen brittle high damping intermetallic compound Ti 3 Sn. An in situ Ti 3 Sn/b-Ti composite with a composition of Ti 77 Mo 3 Sn 20 was prepared by arc melting. The composite simultaneously exhibited high yield strength (500 MPa), large plasticity (35%) and high damping capacity (tan d.0?06). In situ synchrotron high energy X-ray diffraction compression testing revealed that the b-Ti mainly accounts for the plasticity, while Ti 3 Sn provided the strength of the composite.

The joint effect of Si (5,7,and 10 at.%) and at.%) on the structure and mechanical properties of Ti-rich as-cast Ti-Si-Sn alloys is studied. Hypoeutectic alloys with 10 at.% Si are shown to possess the highest level of properties due to a greater volume fraction of the (β*) + Ti 5 Si 3 . eutectic. It is shown that the dependence of strength and hardness of Ti-Si-Sn alloys onSn content is nonmonotonic. The properties improve with increasing tin content to 7-10 at.% due to the solidsolution hardening mechanism. The elastic modulus and plasticity of all the alloys decrease with increasing Sn content. The elastic modulus for the alloys with 7-15 at.% Sn almost halves, decreasing to 65-60 GPa. The level of long-term hot hardness of the alloys at different temperatures depends on Si and Sn content. In general, tin additions increase heat resistance of all the alloys studied. The deviation from the dependence for individual alloys results from variation in their phase composition. The mechanical behavior of Ti-rich Ti-Si-Sn alloys depending on Sn content is determined by the formation of the intermetallic Ti 3 Sn phase.
