摘要	Structure, magnetic properties and magnetostriction of Tb1-x,PrxFe1.93B0.15 (0 less than or equal to x less than or equal to 0.8) alloys are investigated. Addition of a small amount of boron and extra rare earth is beneficial to the formation of a single Laves phase. Single phase Tb1-xPrxFe1.93B0.15 with cubic MgCu2-type structure forms up to x = 0.3 as determined by X-ray diffraction. In the range of high Pr content, the boron atoms preferentially combine with rare-earth atoms to form the Nd2Fe14B-type phase. The results of lattice parameter and Curie temperature show that the Pr solubility limit for Tb1-xPrxFe1.93B0.15 is reached in the range of x from 0.3 to 0.5. Large spontaneous magnetostriction of chi(111) > 2100ppm is observed for the Laves phases in the Tb1-x,PrxFe1.93B0.15 alloys with 0 less than or equal to x less than or equal to 0.3. Linear magnetostriction at room temperature of the single phase Tb1-x,PrxFe1.93B0.15 alloys decreases with increasing Pr content. (C) 2003 Elsevier B.V. All rights reserved.
