Abstract

Abstract

The free-surface velocity profiles of HR2, DT2 and FeMnNi under one-dimensional shock loading were measured by using double-sensitivity VISAR. Combined with the analysis of recovered fragments, dynamic behaviors and spallation phenomena of these materials were studied. Typical triple-wave configurations with phase transition were recorded in DT2 and FeMnNi, but only elastic-plastic double waves were observed in HR2, although the metallographic characters were changed after impact. Multi-spallation and shallow spallation phenomena of DT2 and FeMnNi under homo-thickness target impact were discussed.
