Abstract: FULLY DENSE IRON-BASE ALLOYS CHARACTERIZED BY HAVING A MICROSTRUCTURE EXHIBITING A SUBSTANTIALLY UNIFORMLY DISPERSED CARBIDE PHASE OF PARTICLES SIZE PREDOMINANTLY LESS THAN 3 MICRONS ARE PRODUCED FROM PREALLOYED POWDERS BY RAPIDLY QUENCHING AN ATOMIZED ALLOY CHARGE AND SUBJECTING THE SOLIDIFIED PARTICLES TO THE STEP OF HOT CONSOLIDATION IN AN ENVIRONMENT PROTECTED AGAINST ADMISSION OF OXYGEN TO PRODUCE METAL STOCK DIRECTLY FROM PREALLOYED POWDER BY PLASTIC DEFORMATION.

Abstract: Compositions suitable for tool use and containing from about 10 to about 40% of a material selected from the group consisting of tungsten and molybdenum and mixtures thereof; from about 0.5 to about 4% carbon; at least one reactive metal selected from the group consisting of chromium, vanadium, niobium, tantalum, silicon and manganese; the balance a mixture of iron and cobalt. The alloy is formed by the hot consolidation of pre-alloyed powders and results in an alloy having a uniformly dispersed carbide phase of a grain size less than 3 microns.
