Notes:
The reduction behavior of Al2O3/CuO powder mixtures, prepared from Al2O3/CuO orAl2O3/Cu-nitrate, was investigated by using thermogravimetry and hygrometry. Also, the influence ofpowder characteristics on the microstructure and properties of hot-pressed composites is analyzed. Itwas found that the hydrogen reduction process of nano-sized oxide particles and properties of sinteredcomposites strongly depends on their distribution and size in composite powder. The formationmechanisms of nano-sized Cu dispersions are discussed based on the powder characteristics andreduction kinetics. In addition, the dependence of the microstructure and mechanical properties ofhot-pressed composites on powder characteristics is discussed in terms of the initial size anddistribution of Cu particles
