摘要：

The isothermal section of the Dy-Co-Ti system at 500 degrees C has been investigated in the whole composition range by means of X-ray diffraction, thermal analysis, scanning electron microscopy and energy dispersive X-ray spectroscopy. The only ternary phase DyTixCo12-x is of ThMn12-type structure, space group I4/mmm, and shows a small homogeneity range of 1 <= x <= 1.6. The lattice parameters for DyTixCo12-x with 1 <= x <= 1.56 are a = 0.8336(4)-0.8402(1) nm and c = 0.4691(3)-0.4727(1) nm. Along a constant Dy concentration, the solid solubilities of Ti in the compounds Dy2Co17, DyCo3, DyCo2 and Dy3Co are about 2.0, 2.0, 3.0 and 4.0 at.%, respectively. The TiCo phase has a homogeneity range of 50-54 at.% Co at 500 degrees C and dissolves up to 2.0 at.% Dy. (c) 2009 Elsevier B.V. All rights reserved.
