A manufacturing method of a rare earth alloy strip, rare earth magnets and the rare earth alloy str

PROBLEM TO BE SOLVED : To provide a method for producing a rare earth alloy strip with which variation of segregation amount of α-Fe can be made little and the high quality rare earth alloy strip can be obtained by reducing this segregation amount. SOLUTION : The alloy consisting of essentially of R (at least one kind in the rare earth metal elements containing Y), T (Fe or Fe and Co), and B and substantially having the component R2 T14 B, is heated to >=1300 deg.C to make molten alloy. Then, after reducing hydrogen concentration in this molten steel to <=30 ppm, this molten alloy reducing the hydrogen concentration is cast on rolls and rapidly cooled to obtain the rare earth alloy strip.
