摘      要：Rare-earth(RE)elements,known as“industrial vitamins,have permeated modern lives,especially in high-tech *** the RE elements possess close chemical similarities and have been treated as“one elementin the periodic table,their characteristics differ from each *** RE microalloying effect is the crux to ameliorate the physicomechanical and thermochemical properties of materials,thereby the study of RE-related phase diagrams becomes indispensable to the design and optimization of RE-containing ***,in reality,the knowledge base in this area is considerably scarce compared with that of other commonly-used *** this work,the phase equilibria,phase diagrams,phase transformations,and some recent examples of RE-containing materials design are summarized,with which one can predict the RE solubilities,the RE precipitates,as well as the corresponding service *** attainment of enhanced materials’properties suggests that the thermodynamic rules extracted from the phase diagrams could serve as fundamental criteria for the successful development of novel RE-containing materials.
