Abstract

We have investigated the magnetic properties and the microstructure of Nd₈Fe₈₅B₅Zr₂ bulk nanocomposite magnets consolidated by Spark Plasma Sintering (SPS) method with various sintering temperatures and heating speeds. The volume fractions of a soft magnetic phase (a-Fe or Fe₃B) and a hard magnetic phase (Nd ₂Fe₁₄B) are found to vary sensitively with the sintering temperature, and the samples sintered at 600-650°C show optimum hard magnetic properties. At the same sintering temperature of 600°C, the sample with a higher heating speed of 2400°C/min exhibits larger coercivity and remanence than that with a lower heating speed of 244°C/min, which is attributed to the difference in the grain size.
