Novel Ti3Sn based high damping material with high strength

In this paper, ductile β-Ti was selected to toughen brittle high damping intermetallic compound Ti 3 Sn. An in situ Ti 3 Sn/β-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%)...

Description
Summary:In this paper, ductile β-Ti was selected to toughen brittle high damping intermetallic compound Ti 3 Sn. An in situ Ti 3 Sn/β-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 δ>0·06). In situ synchrotron high energy X-ray diffraction compression testing revealed that the β-Ti mainly accounts for the plasticity, while Ti 3 Sn provided the strength of the composite.
