  • Method For Melting an Alloy Containing a Metal of a High Vapor Pressure
    Publication number: 20090007728
    Abstract: In a method for producing an alloy containing a metal of a low melting point, a low boiling point and a high vapor pressure such as Mg, Ca, Li, Zn, Mn, Sr or the like, a helium containing gas is used as an atmosphere gas for the melting. As a result, the alloy containing the above metal can be produced as an alloy having a targeted chemical composition precisely and safely at a low cost without causing the risk of firing, contamination or the like by active metal fine powder being vaporized. Furthermore, by using the helium containing gas as the atmosphere gas, the quench-solidification of the molten metal can be conducted due to a high thermal conductivity inherent to the helium gas, so that a special alloy can be produced even by the usual melting apparatus.
