英文摘要：

3d transition metal tetraborides （3d-TMB4 ） have attracted considerable attention because of their outstanding properties, such as great mechanical （relatively high bulk modulus and hardness ） , semiconducting, magnetic and superconducting properties. In this paper, the current advance in both theories and experiments of 3d transition metal polyborides （ TM = V, Cr, Mn, Fe and Co） were reviewed involving the synthesis methods, structural evolution and physical properties. Fundamental problems and potential applications of these materials were also proposed.
