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.
