摘要： A process for producing an amorphous ductile brazing foil is provided. According to one example embodiment, the method includes providing a molten mass, and rapidly solidifying the molten mass on a moving cooling surface with a cooling speed of more than approximately 105° C./sec to produce an amorphous ductile brazing foil. A process for joining two or more parts is also provided. The process includes inserting a brazing foil between two or more parts to be joined, wherein the parts to be joined have a higher melting temperature than that the brazing foil to form a solder joint and the brazing foil comprises an amorphous, ductile Ni-based brazing foil; heating the solder joint to a temperature above the liquidus temperature of the brazing foil to form a heated solder joint; and cooling the heated solder joint, thereby forming a brazed joint between the parts to be joined.

摘要： The invention shows possibilities which allow simplified production of implants or prostheses, specifically of dental implants or prostheses, by applying subtractive processes. For this purpose, the invention proposes the use of a precipitation-hardening or solid-solution-strengthening, biocompatible cobalt-based alloy for the production of blanks. Such blanks are provided in the soft state. Subsequently, each component (implant or prosthesis) is produced from the soft blank by means of material-removing machining. Subsequently, a heat-treatment of the implant or prosthesis then takes place to adjust the hardness thereof by means of precipitation hardening or solid-solution formation.
