US Patent 7947134 Process for joining materials using bulk metallic glasses

Methods and compositions for a novel metal-to-metal or material-to-material joining technique using bulk metallic glasses are provided. The method of the current invention relies on the superior mechanical properties of bulk metallic glasses and/or softening behavior of metallic glasses in the undercooled liquid region of temperature-time process space, enabling joining of a variety of materials at a much lower temperature than typical ranges used for soldering, brazing or welding.
