The phase equilibria and thermodynamic parameters, as a function of temperature, of twenty nine ternary and quaternary Fe-base metallic systems containing one of representative elements (Ce, Y, La, Nd, Sm) and S, O, S+O, C, N, Sb, Sn, Pb, P, Cu, Ti, Nb,V respectively, of seven Ni-base metallic systems containg one of the Ce, Y, La elements and S, O, S+O solute element, of twenty Cu-base metallic systems containing Ce or Y and S, O,S+O, Al, Si, Pb, Sn, Zn, Ti, Fe solute element respectively, of ten Al-base metallic systems containing Ce and Mg, Ti, Mn, Zn, Fe, Sn, Pb, Ni, Cu, Si, S solute element respectively were determined by different experimental meth0ds according to the cheracter of systems. The dynamic parameters between rara earth addition agents and S, O, N, H in iron-steel liquid solutions and the data for the effect and application of rare earths in more twenty alloys were obtained. These results of author's group provide a basis for explaining summarily some physic-chemistry effect of rare earth elements on metals and alloys.
