Abstract

The rare earth–iron–transition metal systems are of increasing interest in the search for novel permanent magnet phases. This work reports on the solidification behavior, phase equilibria and stability range of solid phases in the ternary Ce-Fe-Ti system, focusing on the iron-rich region (> 65 at.% Fe) of the isothermal section at 1000 °C. Two ternary phases Ce_1.03Fe_12-xTi_x (x = 0.87–1.02) with ThMn₁₂ structure type and Ce_3.06Fe_27.6Ti_1.4 with Nd₃Fe₂₉ structure type were observed. Magnetic measurements of Ce_1.03Fe_12-xTi_x and Ce_3.06Fe_27.6Ti_1.4 revealed ferromagnetic ordering with Curie temperatures of 550 K and 327 K, respectively.

期刊介绍： The most trusted journal for phase equilibria and thermodynamic research, ASM International''s Journal of Phase Equilibria and Diffusion features critical phase diagram evaluations on scientifically and industrially important alloy systems, authored by international experts. The Journal of Phase Equilibria and Diffusion is critically reviewed and contains basic and applied research results, a survey of current literature and other pertinent articles. The journal covers the significance of diagrams as well as new research techniques, equipment, data evaluation, nomenclature, presentation and other aspects of phase diagram preparation and use. Content includes information on phenomena such as kinetic control of equilibrium, coherency effects, impurity effects, and thermodynamic and crystallographic characteristics. The journal updates systems previously published in the Bulletin of Alloy Phase Diagrams as new data are discovered.
