Abstract: The method for fabricating an R—Fe—B hot-deformed magnet according to the present invention includes: preparing an R—Fe—B magnetic powder; mixing the magnetic powder with a high-melting point metal or a metal compound including the high-melting point metal; press sintering the mixture; and hot-deforming the sintered body by applying heat and pressure, and thus may suppress the growth of crystal grains, and does not need a sintering process of 1,000° C. or more, and the magnetization direction of crystal grains is arranged in one direction even without applying the magnetic field by the hot deformation, and thus, a hot-deformed magnet may be more economically produced. Further, the R—Fe—B hot deformed magnet of the present invention includes a structure in which anisotropic plate-shaped crystal grains of uniform size having an average diameter of 400 to 900 nm are evenly distributed throughout the magnet, and has a uniform and minute size of crystal grains in the magnet, and thus, may secure excellent coercive force, and plate-shaped crystal grains formed by the hot deformation may have excellent residual magnetic flux density because the magnetization direction is arranged in one direction.

Abstract: An R-TM-B hot-pressed and deformed magnet (here, R represents a rare earth metal selected from the group consisting of Nd, Dy, Pr, Tb, Ho, Sm, Sc, Y, La, Ce, Pm, Eu, Gd, Er, Tm, Yb, Lu, and a combination thereof, and TM represents a transition metal) of the present invention comprises flat type anisotropic magnetized crystal grains and a nonmagnetic alloy distributed in a boundary surface between the crystal grains, and thus the magnet of the present invention has an excellent magnetic shielding effect as compared with an existing permanent magnet since the crystal gains can be completely enclosed in the nonmagnetic alloy, so that a hot-pressed and deformed magnet with enhanced coercive force can be manufactured through a more economical process.
