In the present study, the amorphous Ti-Ni-Zr-Cu thin ribbons were successfully prepared through rapid spinning technology. The crystallization temperature of Ti-Ni-Zr-Cu thin ribbon increased with the increasing of heating rate. The activation energy of crystallization for Ti-Ni-Zr-Cu thin ribbon is calculated to be 156 kj/mol, which is remarkably lower than that of the reported Zr-Cu based metal glass due to the smaller negative enthalpy of mixing atomic pairs. The phase constituents of annealed Ti-Ni-Zr-Cu thin ribbons were largely related to the annealing temperatures. The phase constitutes of Ti-Ni-Zr-Cu thin films annealed at the temperatures lower than 850 °C is almost equal, but the lattice constant of various phases is gradually reduced with the increasing of annealing temperatures. In proportion, Ti-Ni-Zr-Cu thin ribbons annealed at the temperatures lower than 750 °C show the higher Vickers hardness, while a noteworthy reduction of Vickers hardness is observed in Ti-Ni-Zr-Cu thin ribbon annealed at 850 °C. Besides, the annealing temperature has a significant effect on the specific heat and corrosion properties, which can be attributed to the distinction of phase constituents.
