Abstract
Dynamic mechanical analysis of magnetic alloys based on the compositions Nd 16Fe76B8 and Nd11.8Fe82.4B5.8 was carried out, It has been shown that the e lastic modulus increased slightly (4-6%) and irreversibly, when the alloys were heated to 400 degreesC and cooled to room temperature. This effect has been found to be detrimental to the intrinsic coercivity of a sintered per manent magnet. (C) 2001 Elsevier Science B.V. All rights reserved.
