ABSTRACT:
Spray cast alloys having reduced porosity and increased ductility are provided as well as a process for the manufacture of the alloys. An effective amount of a reactive metal which reacts with the spray casting atmosphere but not with the desired alloy is dissolved into the alloy prior to spray casting. Preferred reactive metals readily form a nitride which is finely dispersed throughout the spray cast alloy.
