A device including a first part and at least a second part to be assembled to the first part, the first part including a body from which an attachment extends, the attachment defining a housing for the second part, for example as a timepiece hand.

Hand comprising an end piece and assembly method

A method for manufacturing a micromechanical component made of a first material, the first material being a material that can become at least partially amorphous, the method including: a) providing a mold made of a second material, the mold including a cavity forming the negative of the micromechanical component; b) providing the first material and forming the first material in the cavity of the mold, the first material having undergone, at a latest at a time of the forming, treatment allowing the first material to become at least partially amorphous; c) separating the micromechanical component thus formed from the mold.

Method for manufacturing an amorphous metal part

Nickel-free bulk amorphous alloy, formed, in atomic percent, of:

Nickel-free zirconium and/or hafnium-based bulk amorphous alloy

The invention concerns a zirconium and/or hafnium based, beryllium free, solid, amorphous alloy, with the addition of silver and/or gold and/or platinum to increase its critical diameter.

Zirconium-based and beryllium free solid amorphous alloy

The invention concerns a zirconium and/or hafnium based, beryllium free, bulk, amorphous alloy, with the addition of silver and/or gold and/or platinum to increase its critical diameter.
