Joining bulk metallic glass using reactive multilayer foils

We have welded a zirconium-based bulk amorphous alloy using Ni/Al multilayer foils that are capable of producing a self-propagating exothermic reaction. The shear strength of the welded joints increases with both the foil thickness and the pressure that is applied during joining. We measured shear strengths as high as 480 MPa in a compressive single-lap specimen geometry
