PURPOSE:To prevent the deterioration of the characteristics of a magnet by a method wherein alloy powder for adjustment containing an R-Co intermetallic compound phase obtained by a strip casting method is added to main phase alloy powder containing an R2Fe14B phase, which is similarly obtained by the strip casting method, as its main phase, and the alloy powder for adjustment is blended with the main phase alloy powder. CONSTITUTION:60 % or lower of alloy powder for adjustment, which consists of 45 atomic % or lower of R (Provided that the R is at least one kind of an element out of rare-earth elements including Y.) with the remnant of Co (Provided that part of the Co can be substituted for one kind of an element or two kinds of elements of Fe and Ni.) and inevitable impurities and contains an R-Co intermetallic compound phase obtained by a strip casting method, is added to main phase alloy powder, which consists of 11 to 15 atomic % of R (Provided that the R is at least one kind of an element out of rare-earth elements including Y.), 4 to 12 atomic % of B with the remnant of Fe (Provided that one part of the Fe can be substituted for one kind of an element or two kinds of elements of Co and Ni.) and inevitable impurities and contains an R2Fe14B phase, which is obtained by the strip casting method, 2 its main phase, and the alloy powder for adjustment is blended with the main phase alloy powder. |
