Abstract
Different metallic glasses of 40–45 μm thickness were explosively cladded onto metals. The explosive data (amount of explosive and detonation velocity) were changed systematically in a wide range in order to obtain different collision parameters. It was found, that under conditions of explosive welding metallic glasses undergo plastic deformation in different manners. Up to a collision point velocity of vk = 2300 m/s metglas reveals only a shear band deformation mode, leading to many fractures at the plane interphase between metallic glass and metal. At higher velocities a homogeneous type of deformation is observed. The interphase is of wavy nature then.
