Summary:A METHOD OF MAKING A POWDER METAL COMPACT IS DISCLOSED. THE METHOD INCLUDES FORMING A COATED METALLIC POWDER COMPRISING A PLURALITY OF COATED METALLIC POWDER PARTICLES (12) HAVING PARTICLE CORES WITH NANOSCALE METALLIC COATING LAYERS DISPOSED THEREON, WHEREIN THE METALLIC COATING LAYERS HAVE A CHEMICAL COMPOSITION AND THE PARTICLE CORES HAVE A CHEMICAL COMPOSITION THAT IS DIFFERENT THAN THE CHEMICAL COMPOSITION OF THE METALLIC COATING LAYERS. THE METHOD ALSO INCLUDES APPLYING A PREDETERMINED TEMPERATURE AND A PREDETERMINED PRESSURE TO THE COATED POWDER PARTICLES (12) SUFFICIENT TO FORM A POWDER METAL COMPACT BY SOLID-PHASE SINTERING OF THE NANOSCALE METALLIC COATING LAYERS OF THE PLURALITY OF COATED POWDER PARTICLES (12) TO FORM A SUBSTANTIALLY-CONTINUOUS, CELLULAR NANOMATRIX OF A NANOMATRIX MATERIAL, A PLURALITY OF DISPERSED PARTICLES DISPERSED WITHIN THE CELLULAR NANOMATRIX AND A SOLID-STATE BOND LAYER EXTENDING THROUGHOUT THE CELLULAR NANOMATRIX.
