摘 要：The influence of Zr addition on magnetic properties and temperature coefficient for nanocomposite Nd10Fe78.5-xCo5ZrxB6.5 （x=0～4） bonded magnets was investigated. It was found that the room-temperature magnetic properties were remarkably improved with Zr addition due to the grain refinement and increasing volume fraction of the hard magnetic phase. The optimal magnetic properties of Jr=0.689 T, iHc=769.4 kA·m-1 and （BH）max=84 kJ·m-3 were obtained for 2.5% Zr addition. The temperature coefficient of remanence （α） increases slightly and the temperature coefficient of coercivity （β） decreases obviously with increasing Zr content for nanocomposite Nd10Fe78.5-xCo5ZrxB6.5 （x=0～4） bonded magnets.
