ABSTRACT:
A process for producing spherically shaped maraging steel powder particles containing a readily oxidizable metal comprises forming an aqueous solution containing the metal values of iron, cobalt, nickel and molybdenum, in a predetermined ratio, forming a reducible solid material from the solution reducing the solid material to form metallic poweder particles. These particles are agglomerated with a predetermined amount of a second group consisting of at least one readily oxidizable metal selected from the group consisting of aluminum, titanium and vanadium. The agglomerates are entrained in a carrier gas and fed into a high temperature zone and droplets are formed. The droplets are cooled to form essentially spherical shaped particles of a maraging steel alloy containing at least one readily oxidizable metal.
