Abstract
The equation of state, constitutive properties and unloading wave velocities of molybdenum have been determined from free surface velocity profiles on samples shock compressed from a 1400 °C initial state. The equation of state of 1400 °C molybdenum agrees with previous streak camera measurements and the combined equation of state between 12 and 96 GPa is: U_S =4.78 (0.02)+1.42 (0.02)u_p . Unloading wave velocities measured between 12 and 81 GPa range from 6.30 to 7.91 km/s and are 4–8% below extrapolated 25 °C compressional velocities. The yield strength, Y, was found to be 0.79–0.94 GPa, compared with values of 1.3–1.6 GPa from ambient‐temperature experiments.
