What are the effects of Cu doping?

Cu's effect on the strength, microstructure and fracture of the alloys is examined. Cu doping increases toughness and density and decreases porosity of the alloys. A part containing the Cu alloy tolerated 65% more operational cycles than one without. Alloys formed by powder metallurgy are typically porous, which reduces their strength.See all results for this questionThe Effects of Sintering Temperature and Addition of TiH2 pdf effect of fe3p and cu addition on sintering behaviorTherefore, this results in low sintered density. Sintering behavior of Cu can be significantly improved by adding 0.5 wt.% TiH2 which decomposes during sintering, producing hydrogen and effectively reducing the oxide in Cu.
