3.0 wt% nano-meter Cu powder was added into the mixed powders consisting of Cr
Mn and Ti powders and Fe-based powder and the mixture was milled to blend evenly on a high-energy milling machine and was pressure synthesized to shape and then sintered and carbonized in sequence.The microstructures of the powder metallurgically manufactured gears were observed by a scanning electron microscope and a transmission electron microscope;the properties of it are analyzed in comparison with a conventionally manufactur...
