Abstract

The concept of transformation-induced plasticity effect is introduced in this work to improve the plasticity of brittle intermetallic compound Ti₃Sn, which is a potent high damping material. This concept is achieved in an in situ NiTi/Ti₃Sn composite. The composite is composed of primary Ti₃Sn phase and (NiTi+Ti₃Sn) eutectic structure formed via hypereutectic solidification. The composite exhibits a high damping capacity of 0.075 (indexed by tanδ), a high ultimate compressive strength of 1350MPa, 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') of the NiTi component during deformation. The strength of the composite mainly stems from the Ti₃Sn, whereas the NiTi component is responsible for the excellent plasticity of the composite.
