    Evidence for the stable existence of the Fe2Nd phase in the Fe–Nd system (1999)

    Notes: We did directional solidification experiments on Fe20Nd80 alloys at several low cooling rates in order to observe the solidification sequence, displayed along the length of the sample. We also took measurements of the transition temperatures around the eutectic temperature using a Calvet type calorimeter. Our results show that the formation of the eutectic L↔(Nd)+Fe17Nd2 occurs first, and is followed by the eutectic L↔(Nd)+Fe2Nd. The calorimetric measurements give the temperature of the first eutectic to be 688 °C, the temperature of the peritectic formation of the phase Fe2Nd to be 682 °C and the temperature of its eutectoid decomposition as 659 °C. Thermomagnetic measurements give the Curie temperature of the Fe2Nd phase as 250 °C. A new phase diagram for this system is proposed. © 1999 American Institute of Physics.

    Evidence for the precipitation of the Fe2Pr phase in the Fe–Pr binary system (2001)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Directional solidification experiments were employed on Fe–Pr alloys at several low cooling rates in order to observe the solidification sequence displayed along the length of the samples. Measurements of the transition temperatures around the eutectic temperature of this system were also performed using a Calvet-type calorimeter. The results show the precipitation of the Fe2Pr phase and its peritectic formation, described as Fe17Pr2+L→Fe2Pr. The calorimetric measurements give the temperature of this reaction as being 669 °C. The system presents only one eutectic reaction at 664 °C, described as L→Fe2Pr+Pr, with a feathered morphology under metallographic analysis. Thermomagnetic measurements give the Curie temperature of the Fe2Pr phase as 44 °C. A sequence of reactions during solidification of the alloys around the eutectic point for the Fe–Pr binary system is proposed. © 2001 American Institute of Physics.

    Field-induced sharp ferroelectric phase transition in Sr0.66Ba0.34Nb2O6 relaxor ferroelectric (2001)

    Notes: Field-induced sharp ferroelectric phase transition was observed in Sr0.66Ba0.34Nb2O6 single crystals. The peaks of the real and imaginary parts of dielectric permittivity arise upon cooling under weak dc bias electric fields and subsequently heating under zero fields or upon cooling under zero fields and subsequently heating under weak electric fields. The applied electric field cancels the random fields that destroy the phase transition and give rise to low temperature domain state if E=0. These results strongly suggest that the SBN system belongs to the random field Ising universality class, a rare case among structural phase transitions. © 2001 American Institute of Physics.
