- Abstract
- The microstructure of nano-sized oxide particles formed in Fe-5Y(2)O(3) alloys uniaxial-hot-pressed at 1150 degrees C for 1 hour after a mechanical alloying of 95 wt%Fe and 5 wt%Y2O3 powders was examined. Several kinds of nano-sized oxide particles were found in the uniaxial hot pressed Fe-5Y(2)O(3) alloy, and their crystal structures seemed to be Y2O3, Y3Fe5O12 and YFeO3. The oxide particles with diameters of about 20 nm showed a semi coherent relationship with the matrix while those more than 200 nm in diameter exhibited a non-coherent relationship with the matrix, and this tendency appeared to be independent of the kind of oxide particles.
