摘要：
The effect of cobalt content in sintered magnets of the Nd(Pr) – Dy – Fe – Co – B system on the sintering temperature, at which the density is equal to 99% of the maximum value and the coercive force Hci is the highest, is determined. The main components forming the liquid phase in sintering of the materials are determined. It is shown that the addition of (Pr, Dy)(Fe, Co)2B2 intermetallic to alloy (Pr, Dy) – (Fe1 – yCoy) ( y ≈ 0.5) during the operation of fine milling of sintered magnets has a positive effect on the value of Hci.
