| Abstract |
| The microstructure of nano-sized oxide particles formed in Fe-5Y2O3 alloys uniaxial-hot-pressed at 1150 ℃ 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-5Y2O3 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. †(Received September 11, 2015; Accepted January 9, 2016) |
