Abstract: Magnetic properties and microstructure of directly quenched Nd9.5Fe72.5Ti3B15 and Nd9.5Fe71.5Ti2.5Zr0.5Cr1B14.5C0.5 rod magnets with various diameters of 0.7–1.5mm have been investigated. TMA shows that all the studied alloy rods mainly consist of a large amount of a 2:14:1 phase. Although the magnetic properties of these two alloys are decreased with the increase of diameter, the latter alloy, consisting of more elements, can preserve attractive magnetic properties up to a larger diameter of 1.3mm, due to the grain refinement effect induced by multi-component substitutions.
