Shock-induced Preferred Disorder in Solids

WE reported1 that shock pressures higher than 190 kbar induce pronounced crystallographic alterations (which can be detected by X-ray diffraction techniques) in three meteoritic minerals: body-centred cubic α-Fe (kamacite), orthorhombic Fe3C (cohenite) and tetragonal Fe3P (schreibersite). We suggested that such alterations should also be produced by shock… (More)
