Abstract
Phase formation and magnetic properties of (Nd1−xYx)14Fe80B6 (x = 0.1–0.8) alloys were investigated experimentally by x-ray diffraction (XRD) and vibrating sample magnetometer (VSM). The phase structure analysis reveals that the as-cast (Nd1−xYx)14Fe80B6 alloys were made of 2:14:1 phase with tetragonal Nd2Fe14B-tpyed structure, REFe2 and α-Fe phases, while the melt-spun ribbons are composed of 2:14:1 phase and α-Fe Phase. Based on the magnetic measurements, the remanence (Br), the coercivity (Hcj), the maximum magnetic energy product ((BH)max) and the Curie temperatures (Tc) of (Nd1−xYx)14Fe80B6 ribbons reduces gradually with increasing Y substitution. The relatively high coercivity (6.75 kOe) of (Nd0.4Y0.6)14Fe80B6 ribbon with high Y substitution was achieved, which indicates that good magnetic properties of Nd–Y–Fe–B ribbons would be obtained through the design of alloy composition and phase formation.
