    Abstract: The invention relates to a method for mounting at least one decorative element (3) on a support (2) comprising the steps of: a. taking a support (2) provided with at least one cavity (4); b. taking at least one decorative element (3); c. filling said cavity with a composite filler material comprising at least one metal powder and at least one organic binder and having, at the moment of filling, a viscosity comprised between 1,000 mPa·s and 1,000,000 mPa·s; d. heating the composite filler material to a higher temperature than its melting point to make it liquid; e. allowing the filler material to cool to form a substrate (6); f. making at least one housing (8) in said substrate (6); g. mounting said decorative element (3) in said housing (8). The present invention also concerns a decorative support (2) provided with at least one cavity (4) filled with said filler material forming a substrate (6) in which at least one housing (8) is formed, said housing (8) being arranged to receive said decorative element (3).

    Abstract: A process for assembling a device including first and second parts made of first and second materials, respectively, and a third part made of a third material that acts as an intermediate part enabling the assembling, the process including: providing a preform made from an at least partially amorphous metal material capable of increasing its volume under temperature and pressure conditions; placing the first and second parts with the preform between two cavity plates having, the negative shape of the device; heating the assembly to a temperature between the glass transition temperature and the crystallization temperature of the preform to enable, at latest during the heating, the preform to be in a form of a foam and enable expansion of the preform to fill the negative shape of the device and form the third part; cooling the assembly to solidify the preform and separate the device from the cavity plates.
