文摘

Intermetallic compound Ti3Sn was shown to exhibit a martensitic transformation from parent hexagonal to orthorhombic phase leading to high damping capacity and low Young's modulus of the material. Present work is dedicated to studying the mechanical behavior of non-stoichiometric intermetallic compound Ti75.5Sn24.5 with 1 at% and 3 at% of Zr and Al additions by dynamical mechanical analysis and compressive tests. Zr and Al additions decrease martensitic transformation temperatures and widen the temperature hysteresis. Studied alloyed compositions exhibited higher Young's modulus and compressive yield stress and lower damping capacity than binary Ti75.5Sn24.5 alloy.
