Abstract Ni0.25Fe0.75Zr3 metallic glassy ribbons were annealed in evacuated quartz ampoules beyond the crystallization temperatures Tx ~655 K over the range 773 to 1,173 K for varying periods of time. The resistivity of samples annealed over the temperature range 923 to 1,073 K for periods less than four hours increased as a function of decreasing temperature, while it decreased for samples annealed for more than four hours or at temperatures below 923 K or above 1,073 K for any period of time. All the annealed samples were found to contain only Ni, Fe and Zr from energy dispersive X-ray EDX analyses. View Full-Text
