Abstract : This document describes a method for adding alloying elements having relatively low boiling points to base metal shaving relatively high melting points. The base metal is combined with the melting point-lowering metal; or metalloid and to this mixture is added the desired alloying metal or metals. No special equipment is required for this method. The first metals included within the scope of this invention are selected from the group consisting of Ba, Ca, Li, Mg and An. Each of these metals has a relatively low boiling point and, with the exception of Zn, a relatively low density. The more refractory base metals included within the scope of this invention are selected from the group consisting of IB, IVB, VB, VIB and VIII of the Periodic Table of the Elements. Of particular interest are Cu from IB, Ti and Zr from IVB, Nba and Ta from VB, Cr and W from VIB and Fe, Co and Ni from VIII.
