説明
<p>Fe-Al alloy powder was mixed with Fe2O3, NiO and SiO2 powders, and the mixed powders were cold-pressed and annealed at 800°C. Nano-sized Al-oxides were precipitated within the α-Fe matrix of the Fe-Al alloy powder mixed with Fe2O3 and NiO. On the other hand, oxide precipitation was not confirmed within the α-Fe matrix of the SiO2 doped alloy. This difference is caused by the thermodynamic stability of the oxides, where Fe2O3 and NiO are not in equilibrium with α-Fe so that they are dissolved in the α-Fe matrix to form more stable Al-oxides, while SiO2 is in equilibrium with α-Fe thus the chemical driving force for the Al-oxide precipitation was small.</p>
