The detection device comprises a cold finger which performs the thermal connection between a detector and a cooling system. The cold finger comprises at least one side wall at least partially formed by an area made from the amorphous metal alloy. Advantageously, the whole of the cold finger is made from the amorphous metal alloy.

Vessels used for melting material to be injection molded to form a part are described. One vessel has a body formed from a plurality of elongate segments configured to be electrically isolated from each other and with a melting portion for melting meltable material therein. Material can be provided between adjacent segments. An induction coil can be used to melt the material in the body. Other vessels have a body with an embedded induction coil therein. The embedded coil can be configured to surround the melting portion, or can be positioned below and/or adjacent the melting portion, so that meltable material is melted. The vessels can be used to melt amorphous alloys, for example.

Embodiments relate to a cutting tool comprising a base material, an amorphous alloy forming an amorphous alloy matrix layer; and a plurality of diamond particles embedded in the amorphous alloy matrix layer forming a cutting edge, wherein the amorphous alloy matrix layer bonds the plurality of diamond particles and the base material.

An external part element or component for a timepiece or piece of jewellery made with a fibre-reinforced polymer matrix composite material, this external part element including on at least one of the faces thereof at least one cavity wherein an insert made of metallic glass is housed. A method for manufacturing such an external part element is also described.

An embodiment relates to a material comprising a ceramic formed from an amorphous metal alloy (amorphous metal ceramic composite), wherein the composite exhibits a higher corrosion resistance than that of Haynes 230 when exposed to molten chlorides such as KCl or MgCl.sub.2 or combinations thereof at temperatures up to 750 C. Yet, another embodiment relates to a method comprising obtaining a substrate, forming a coating of an amorphous metal alloy, heating the coating, and transforming at least a portion the amorphous metal alloy into an amorphous metal ceramic composite.

A method for producing a timepiece component (100) made of amorphous metal alloy, the production method comprising a step (E1) of producing a first preform made of amorphous metal alloy, then a step (E2) of hot drawing the first preform to obtain a second preform, then a step (E3) of machining the second preform.
