We have studied the crystallization, crystal structure, microstructure, and magnetic properties of melt-spun ribbons of R6(Fe-Nb)88B6 with RNd, Pr, Dy, Tb and Nd3.5(Fe-Nb)93B3.5 consisting of a mixture of exchange-coupled magnetically hard R2Fe14B

We have prepared a new series of R-Fe-B alloys with R=Nd, Pr, and Dy having the Y/sub 3/Fe/sub 62/B/sub 14/ structure using the melt-spinning technique. This metastable phase when annealed at higher temperatures transforms to the R/sub 2/Fe/sub 14/B/

The objective of this study was to produce a nanocrystalline Sm(CoFeCuZr)/sub z/ magnet consisting of magnetically hard Sm/sub 2/Co/sub 17//SmCo/sub 5/ phases and soft Fe(Co) phases. For this we have prepared melt-spun ribbons of Sm(Co/sub 0.65/Fe/su

The crystallization behavior of Nd/sub x/Fe/sub 93-x/Nb/sub 1/B/sub 6/ melt-spun ribbons was investigated using calorimetric techniques. The crystallization products were identified by X-ray diffraction and thermomagnetic measurements. Samples with x

The hysteresis behavior of nanocomposite R/sub 2/Fe/sub 14/B//spl alpha/-Fe magnets with R=Nd and Pr was investigated at low temperatures. The room temperature coercivity depends on annealing with a peak value at 700/spl deg/C. The low coercivity of

We have studied the crystallization, crystal structure, microstructure and magnetic properties of R‐Fe‐B (R=Nd,Pr,Dy,Tb) based melt‐spun ribbons consisting of a mixture of R2Fe14B and α‐Fe phases. All the samples crystallize first to α‐Fe

High isotropic remanences and energy products have been obtained in melt‐spun Nd‐Fe‐B samples with a fine grained mixture of α‐Fe and Nd2Fe14B1 containing more than 50 wt % of α‐Fe. Reduced remanences as high as 0.78 with high saturation

The coercivity of melt-spun Pr-Fe-B magnets has been found to increase with small additions of Al, Cu, and Zn. Systematic high-resolution electron microscope (HREM) observations were carried out to reveal the structural changes that might occur with

Addition of small amounts of Cu and Zn was found to enhance the coercivity Hc of Pr‐Fe‐B melt‐spun magnets. 1.5% Cu addition increases the coercivity by 6 kOe over the Cu free value of 18 kOe while 3% Zn increases Hc by 8 kOe. Both of the addit
