  Isothermal section of the Ho–Co–Fe system at 773K

  摘要：

  The 773 K isothermal section of the phase diagram of the Ho-Co-Fe ternary system was investigated by using X-ray diffraction technique, metallographic analysis and scanning electron microscopy with energy dispersive analysis. The isothermal section of the ternary system consists of 6 three-phase regions, 16 two-phase regions and 11 single-phase regions. Three pairs of corresponding compounds of Ho-Co and Ho-Fe systems, i.e., Ho(2)Co(17) and Ho(2)Fe(17), HoCo(3) and HoFe(3), HoCo(2) and HoFe(2), form a continuous series of solid solution. At 773 K the compound Ho(6)Fe(23-x)Co(x) was found to have a wide homogeneity range from 0 to 29 at.% Co. The maximum solid solubilities of Fe in Co, Ho(2)Co(7), Ho(12)Co(7) and Ho(3)Co were determined to be about 10, 9, 2 and 5 at.% Fe, respectively. The maximum solid solubility of Co in Fe is found to be 78 at.% Co. (C) 2010 Elsevier B.V. All rights reserved.

  Specific heat measurements were performed in wide temperature range T = 2-300 K for the R3Co (R = Er-Gd, Y) compounds. Using values of the Sommerfeld coefficient and Debye temperature estimated for Y3Co compound, the Debye temperatures, phonon and conduction electron contributions as well as magnetic contribution to the specific heat were estimated for all other R3Co compounds.
