ABSTRACT:
A method of adding trace elements to a base metal, particularly useful for adding yttrium or a rare earth metal to titanium. This method is especially useful for adding these and other trace elements which have low solubility in the base metal or a high melting point and tend to form undesirable segregates in the microstructure. The invention overcomes this difficulty by dispersing finely divided particles of trace element in a vehicle before adding the trace element to a melt charge. The vehicle may be finely divided base metal, or a solvent and diluent.
