Abstract Scope In the present work, various Mg-RE (Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) binary alloys had been fabricated by casting and subsequent hot extrusion as models. The microstructure and mechanical properties had been studied, and their degradation behavior in SBF had been tested, with the ion release behavior being monitored, and the cytotoxicity and hemocompatibility had been evaluated with different cell lines. Animal testing on the in vivo performance of the binary Mg-RE alloys were undertaken. The relationship between the in vitro and in vivo biocompatibility and the location of the RE element in the periodic table had been discussed and the best alloying elements for the rare earths elements in magnesium had been screened.
