发明名称 ALLOY MATERIAL FOR R-T-B SYSTEM RARE EARTH PERMANENT MAGNET, METHOD FOR PRODUCING R-T-B SYSTEM RARE EARTH PERMANENT MAGNET, AND MOTOR
摘要 <p>Disclosed is an alloy material for R-T-B system rare earth permanent magnets, which contains an R-T-B system alloy containing R, T and B, and a high melting-point compound having a melting point of not less than 1,080°C.  (In this connection, R represents at least one element selected from a group consisting of Nd, Pr, Dy and Tb, and Dy or Tb is essentially contained in the R-T-B system alloy in an amount of 4-10% by mass; T represents transition metal(s) essentially including Fe; and B represents boron which can be partially substituted by carbon or nitrogen.)</p>
