Yttrium also finds application in titanium alloys where at concentrations of the order of 200 ppm it improves the ductility and ease of fabrication of vacuum arc-melted alloys. It is also used to improve the strength of magnesium castings and when used in combination with zirconium, as little as 100 ppm yttrium increases the conductivity of aluminium transmission lines by as much as 50%. 

The temperature capability tif nickel-basc alloys has been improved markedly bv processing techniques such as vacuum arc melting. 

A number of investigations on ultrasound effects have been carried out in the U.S. these include studies on vacuum-arc melting of nickel-containing alloys and steels under an ultrasonic field [19], on a mechanism of grain refinement in as-cast alloys [20,23], on amorphization of metals (Suslick [21]), on ultrasonic atomization (Grant [22]), and on production of composite materials [23].

It s an ongoing study, further studies have been carried out with using different initial mixture ratios (Ni0/Cr203, etc.), with using Fe-scrap and mill-scale. Also the refinement studies will be realized by using mini vacuum arc melting furnace.
