abstract = "Yield and spall strengths of pure polycrystalline Ti (99.99% Ti) studied in a series of planar impact experiments with initial sample temperature ranging from 20 to 1000°C. In a separate series of experiments the temperature dependence of the longitudinal speed of sound in Ti was measured on the basis of reverberation of the stress pulse generated in the 3-mm Ti sample by a 1-mm aluminum impactor. In all the experiments the velocity of the sample free surface was continuously monitored by VISAR. It was found that the yield strength of titanium α-phase has a 250-MPa maximum at ∼600°C followed by a 100-MPa minimum at ∼800°C. Further heating towards the α-β transformation temperature, 882°C, results in an increase of the strength up to 200 MPa. In β-domain the yield strength of titanium stays constant and close to 100 MPa. The spall strength of titanium drops from ∼ 3 GPa at 800°C to ∼ 2.5 GPa at 840°C, indicating the shock-induced α-β transformation. Possible plastic deformation mechanisms responsible for the temperature variations of titanium strength are discussed.",
