“…Pure magnesium has the best damping capacity among various metallic materials. 8 However, poor mechanical properties of pure magnesium limit its more widespread applications. Therefore, the applications of high strength and high damping magnesium alloys were considered by alloying or plastic deformation.…”

1ZK60 alloy strip with 3?5 mm thickness which produced by Twin Roll Casting (TRC) was used in this paper. The effect of hot rolling and sequential annealing on microstructure and damping capacity of the ZK60 alloy was studied by using optical microscope (OM) and dynamic mechanical analyzer (DMA). The dendrite structure was present in TRC ZK60 alloy strip before and after annealing heat treatment. The small and equiaxed recrystallised grains were obtained after annealing at 3508C for 10 3 s in hot rolled ZK60 alloy sheet. The hot rolling and the sequential annealing improved the room temperature mechanical properties and damping capacity of TRC ZK60 alloy. The tensile strength, yield strength and elongation of as-annealed TRC ZK60 alloy strip and hot rolled ZK60 alloy sheet were 207, 184 MPa, 2?6% and 418, 349 MPa, 18?6%, respectively. The room temperature damping value (Q 21) of ZK60 strip and ZK60 alloy sheet after annealing heat treatment was 0?0085 and 0?0119, respectively. The damping peaks were present in ZK60 strip and ZK60 alloy sheet after annealing heat treatment. The activation energy of the ZK60 strip and ZK60 alloy sheet were 110?63 and 90?18 KJ mol 21. The value of activation energy of ZK60 alloy sheet was very close to the boundary activation energy of pure magnesium (92 KJ mol 21 ). The damping peak of ZK60 alloy sheet after annealing treatment was the grain boundary peak.

High damping NiTi/Ti3Sn in situ composite with transformation-mediated plasticity

et al. 2014

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.

“…[1][2][3] High damping materials can convert the mechanical energy of vibration into heat, thus eliminating noise and vibration effectively, and are finding increasing applications in mechanical structures. [3][4][5] Apart from thermoelastic damping, the majority of damping mechanisms in metallic materials relate to the stressn induced movement of crystalline defects.…”

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.
