Abstract

Abstract

Dynamic compression tests of W-Ni-Mn alloy were performed, using cylindrical specimens 5 mm both in diameter and long with the split Hopkinson pressure bar (SHPB) technique. Both sections and fracture surfaces of specimens were observed with SEM. Connected with true stress-strain curves of specimens, it was found that adiabatic shear bands in sections of specimens appeared distinctly when specimens took place about 45% true strain. W-Ni-Mn alloy is easier to come into being adiabatic shear band(ASB) than the conventional tungsten heavy alloy, and has higher adiabatic shear sensitivity.
