ABSTRACT:
An alloy difficult to produce by conventional electrodeposition techniques is produced by electrodepositing at least one metal selected from the group comprising nickel, up to 50% cobalt, and iron with particles incorporating metal in chemically combined state. The particles contain a reactive element, such as carbon, nitrogen, and boron, and a metallic element, such as chromium, molybdenum, and tungsten. The electrodeposit of the particles in a metal matrix is treated in a reducing atmosphere so that the particles react, releasing at least some of their incorporated metal into the matrix to form the alloy while transferring the reactive element to the reducing atmosphere.
