THE EFFECT OF HEAT TREATMENT UNDER VARIOUS CONDITIONS ON MICROSTRUCTURE OF SINTERED (Nd,Pr,Dy)-Fe-B MAGNETS
Original language description
The use powder mixtures, which consists of strip-casting (Nd,Pr)-Fe-B alloy and DyH2 hydride, allows the high-coercivity magnets to be prepared.The stability of the reached high magnetic characteristics in the course of both low- and high-temperature heat treatments was shown to be related to the evolution grain structure of the magnets. The microstructure and chemical composition of the permanent magnets was studied by electron microscopy (SEM/EDX) using a Quanta 450 feg microscope. Electron microscopic studies of their microstructure have demonstrated annealing-induced changes in the thickness and continuity of (Nd,Pr,Dy)2Fe14B-phase grain boundaries and the shape of triple junctions of the grains. Electron microprobe analysis of triple junctions hasrevealed the presence of various (Nd,Pr,Dy)-O oxides such as (Nd,Pr,Dy)O, (Nd,Pr,Dy)2O3 and (Nd,Pr,Dy)O2. The studies performed allow us to conclude the effect of the heat treatment of the principal structural and magnetic characteristic
