Notes:
This investigation was conducted to study the effect of Al(Cr) content in Cu-Al(Cr)pre-alloyed powders on the distribution of Al2O3(Cr2O3) particles formed by internal oxidation. Theresults show that the distribution of Al2O3 particles is different with the change of Al content in Cu-Alsystem. When the Al content is above 1.2wt.%, the Al2O3 particles tend to distribute along the grainboundaries of copper matrix , whereas when the Al content is above 2.0 wt.%, the Al2O3 particleshave distributed along the grain boundaries. However, it is interesting to note in Cu-Cr system thatmost of the formed Cr2O3 particles prefer to distribute in the grain of copper matrix when the Crcontent is less than 5wt.%, which is quite different from that of Cu-Al system
