Abstract
A process for producing a blend of maraging steel alloys and an oxidizable metal comprises forming an aqueous solution or iron, cobalt, nickel and molybdenum in a predetermined ratio. Thereafter, a reducible solid material containing the metals is produced from the solution. The solid material is reduced to metallic powder particles which are entrained in a carrier gas and fed into a high temperature zone to form droplets which are cooled to form essentially spherical shaped metal alloy particles. These particles are combined with a predetermined amount of at least one easily oxidizable metal selected from the group consisting of aluminum, titanium and vanadium to form a relative uniform blend of the spherical shaped particles and the readily oxidizable metal.
