| 中文摘要 | We have studied the effect of the atomic disorder-order transformation on remanence enhancement and coercivity in Fe-Pt-based materials by isothermal annealing at temperatures well below the transformation point. We also investigated the effect of the annealing temperature and the effect of various types of additives. The relative amount of the low-temperature hard-magnetic face-centered-tetragonal (FCT) phase precipitated in the high-temperature magnetically soft face-centered-cubic (FCC) phase was determined by means of X-ray diffraction. As a function of annealing time and annealing temperature, particle size and relative amount of the FCT phase increased at the cost of the FCC phase. These changes were followed by means of magnetic measurements. We observed a continuous increase in coercivity with increasing annealing time, eventually reaching a maximum. The Kneller-Hawig model was used to explain the occurrence of remanence enhancement and the continuously changing degree of exchange coupling between the magnetically soft and hard phase. The suitability of Fe-Pt based alloys in dental applications is discussed. (C) 2001 Elsevier Science B.V. All rights reserved. |
