Abstract
The present invention relates to an infiltrated ferrous powder metal part containing certain additives, yielding a radically improved unnotched impact strength without sacrificing tensile strength. Fatigue strength is also improved. In addition, improved dimensional control is obtained during infiltration. The microstructure is also improved, with smoothing or rounding of the formerly sharp angled copper filled pores. The invention also comprises the method of achieving these results.
