Explosive Welding of metallic glasses onto metals

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 v k = 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.
