摘要：

Shock compression experiments on a new kind of 47Zr45Ti5A13V alloys at pressures between 28 and 200 GPa are performed using a two-stage light gas gun.The Hugoniot data are obtained by combining the impedance-match method and the electrical probe technique.The relationship between the shock wave velocity Us and particle velocity up can be described linearly by Us = 4.324（±0.035） + 1.177（±0.012）up.No obvious evidence of phase transition is found in the shock compression pressure range.The calculated Us—up relationship obtained from the additive principle is different from the experimental data,indicating that the α→β phase transition occurs below28 GPa.The Griineisen parameter 7 obtained from the experimental data can be expressed by γ = 1.277（po/p）.The zero-pressure bulk modulus Bos = 97.96 GPa and its pressure derivative B'os = 3.68.The P-V-T equation of state for 47Zr45Ti5A13V is given using the Vinet equation of state to describe the cold curve and the Debye model for the thermal contributions.
