The adiabatic shear bands (ASBs) in AM60B magnesium alloy under ballistic impact at a velocity of 1 km.S-1 were studied by means of optical microscope (OM), scanning electron microscope (SEM), and transmission electron microscope (TEM).The results show that two kinds of ASBs can be observed on the polished surface of the crater.One is formed near the crater and propagates along crater tim, and the other is formed from the edge of crater and extends into the matrix.The ASBs can be served as preferential sites for crack formation and propagation.
