Dynamic mechanical behavior of intermetallic Ti3Sn
2010
Damping and Young’s modulus have been measured in single-phase Ti 3 Sn using resonant and dynamic mechanical techniques. The compound demonstrates unusual non-linear behavior. Elasticity decreases with strain, but increases with both frequency and temperature (343–673 K); damping is unusually high and decreases with frequency, remains unchanged with strain and shows peaks at 190 and 310 K. Although the mechanisms of energy dissipation are presently unknown, the results suggest the occurrence of a phase transition at about 350 K.
