The Behavior of Ni, Ni-60Co, and Ni3Al during One-Dimensional Shock Loading

“…Dandekar and Martin [19] showed that the HEL of Mar-M200 underwent significant precursor decay (i.e., reducing with specimen thickness). Zaretsky et al [20] examined the mechanical behavior of two superalloys as a function of temperature. They showed that the strength of these materials gradually decreased with temperature until reaching an abrupt reduction between 550°C and 600°C.…”

Mechanical Properties of Shock Treated Aluminium Alloy Al 2024-T4

“…The shock velocity D in the target corresponding to this particle velocity is obtained to be 5.73 km/s from the known Hugoniot of Al2024 alloy [10]. The Hugoniot elastic limit ( HEL σ ) and spall strength (σ s ) are determined from the free surface velocity profile using the following expressions [1,8,9]: E(GPa) Figure 1 The fringe shift recorded for S and P waves (top) and corresponding free surface velocity profile (bottom) determined from the fringe shift for Al2024-T4 alloy…”
