摘要
Three kinds of bulk-type ultrafine TixSny/TiNi （TixSny represents Ti3Sn, Ti2Sn, and TisSn3 or Ti6Sns） composites with homogeneous eutectic microstructure were prepared by arc melting. The composites exhibit high damping capacity （tan6 greater than 1 x 10-2） and enhanced mechanical strength （the highest fracture strength is 2.15 GPa）. The damping capacity originates from TiNi and Ti3Sn, while the eutectic contributes to the mechanical strength.
