Abstract:

X-ray diffraction line broadening studies were conducted on polycrystalline nickel samples subjected to shock pressures of 70, 150, 270, 375 and 615 kilobars. Lattice strains and small domain sizes are given as a function of shock pressure. Results indicate a linear correlation between lattice strains and shock hardening. A discontinuity in both the hardening and lattice strain data at a shock pressure between 270 and 375 kilobars suggests the possible occurrence of twinning. Author
