Abstract
A powdered material and a process for producing the material are disclosed. The powdered material consists essentially of iron group based and chromium based spherical particles. The material is essentially free of elliptical shaped material and elongated particles having rounded ends. The material has a particle size of less than about 20 micrometers. The process for making the spherical particles involves mechanically reducing the size of a starting material to produce a finer powder the major portion of which has a particle size of less than about 20 micrometers. The finer powder is entrained in a carrier gas and passed through a high temperature zone at a temperature above the melting point of the powder to melt at least about 50% by weight of the powder and form the spherical particles of the melted portion. The powder is then directly solidified.
