    Abstract: Exemplary embodiments described herein related to methods and systems for casting metal alloys into articles such as BMG articles. In one embodiment, processes involved for storing, pre-treating, alloying, melting, injecting, molding, etc. can be combined as desired and conducted in different chambers. During these processes, each chamber can be independently, separately controlled to have desired chamber environment, e.g., under vacuum, in an inert gas environment, or open to the surrounding environment. Due to the flexible, independent control of each chamber, the casting cycle time can be reduced and the production throughput can be increased. Contaminations of the molten materials and thus the final products are reduced or eliminated.

  • Patent number: 8403025
    Abstract: In a process for the preparation of inorganic sample disks for analysis, the sample, in powdered form, is mixed with a powdered reagent flux which has been pre-melted. In an inert gas atmosphere, the mixture is placed in a graphite crucible and heated to a temperature slightly above 1000° C. After the flux dissolves the sample, a homogenous mix is produced. This mix is then poured into a graphite mold, the bottom of which contains a molten pool of an inert metal, such as gold, which acts as a smooth receiving surface. Upon cooling, the material in the mold solidifies, resulting in a glassy disk that can be analyzed. Cooling can be accelerated by making use of a cooling fluid that has a substantially higher thermal capacity than air.

According to a first aspect melting of alloying elements and casting of the biocompatible precious metal alloy are carried out in a process chamber (11) being provided with a process gas of predetermined composition. A burning flame (19) of a hydrocarbon-containing gas provides low oxygen and water content. According to a second aspect post-processing of a precious metal alloy is made in atmosphere provided by the process gas to form the biocompatible precious metal alloy object. The biocompatible precious metal alloy object manufactured according to the invention has a low probability of causing sensitisation when in contact with the human body.

  • Publication number: 20100212855
    Abstract: The invention relates to a casting process for an aluminum alloy containing at least about 0.1% of Mg and/or at least about 0.1% of Li in which a liquid surface of said alloy is put into contact with a dried gas including at least about 2% of oxygen by volume and with a water partial pressure lower than about 150 Pa throughout most of the solidification process. The invention makes it possible to cast the most oxidable aluminum alloys, in particular aluminum alloys containing magnesium and/or lithium, without using additives such as beryllium and/or calcium and without using expensive devices and/or gases, to obtain cast ingots free from surface defects and pollution, in complete safety.

  • Publication number: 20100132906
    Abstract: During the casting of the metal article, a mold is lowered from a furnace assembly into a body of an inert gas. A stream having a thermal conductivity greater than the thermal conductivity of the inert gas is directed against a first portion of the mold to initiate solidification of molten metal in the first portion of the mold. The stream is subsequently directed against portions of the mold disposed in the body of inert gas and disposed above the first portion of the mold to initiate solidification of molten metal and portions of the mold above the first portion of the mold. The stream may be formed of a molten metal. Alternatively, the stream may be formed of an inert gas in which particulate is entrained.
