ABSTRACT:
A nanostructured steel alloy is presented. Preferably, the nanostructured steel is of the M50 type, and comprises iron, molybdenum, chromium, vanadium and carbon. In accordance with an important feature of this invention, the grain size of the steel is in the nanometer range. In accordance with the method of the present invention, the nanostructured steel is prepared via chemical synthesis from iron, molybdenum, chromium and vanadium starting materials. Decomposition of metal precursors or reduction of metal halides is followed by consolidation of the resulting nanostructured steel powders into bulk steel. The nanostructured steel of this invention finds particular utility in the manufacture of cutting tools and bearings.
