7. Способ получения спеченного магнита на основе R-Fe-B по п. 1, включающий в себя этапы:
придания формы порошку сплава, с образованием неспеченной прессовки, причем порошок сплава получают путем тонкого измельчения сплава, состоящего в основном из 12-17 ат.% R, который представляет собой, по меньшей мере, два элемента из иттрия и какого-либо из редкоземельных элементов и в основном содержит Nd и Pr, 0,1-3 ат.% M1, который представляет собой, по меньшей мере, один элемент, выбранный из группы, состоящей из Si, Al, Mn, Ni, Cu, Zn, Ga, Ge, Pd, Ag, Cd, In, Sn, Sb, Pt, Au, Hg, Pb и Bi, 0,05-0,5 ат.% M2, который представляет собой, по меньшей мере, один элемент, выбранный из группы, состоящей из Ti, V, Cr, Zr, Nb, Mo, Hf, Ta и W, 4,8+2×m - 5,9+2×m ат.% B, где m означает атомную концентрацию M2, до 10 ат.% Co, и остальное - Fe,
спекания неспеченной прессовки при температуре 1000-1150°C,
охлаждения спеченного компакта до температуры 400°C или ниже при скорости 5-100°C/мин, и
подвергания старению, включающего в себя подвергание спеченного компакта воздействию температуры в диапазоне 400-600°C, причем данная температура является более низкой, чем перитектическая температура фазы R Fe(Co)-M1 для образования фазы R-Fe(Co)-M1 на границе зерен, и охлаждения до температуры 200°C или ниже.
8. Способ по п. 6 в котором сплав содержит Dy, Tb и Ho в общем количестве 0-5,0 ат.%.
