摘　　要：The magnetostrictive effects of substituting A1 for Fe in Pr（AlxFe1-x）1.9 （x = 0.0, 0.02, 0.05, 0.10） alloys between 5 K and 300 K were investigated. The substitution decreases the Curie temperature and the value of λ111. Fortunately, the substitution slightly increases the magnetostriction in a low magnetic field, which imbues these materials with potential advantages for applications. Rotation of the easy magnetization direction （EMD） from [ 111 ] to [ 100] in the Pr（A10.02Fe0.98）1.9 alloy as temperature decreases was detected by step scanned XRD reflections.The magnetostrictive effects of substituting A1 for Fe in Pr（AlxFe1-x）1.9 （x = 0.0, 0.02, 0.05, 0.10） alloys between 5 K and 300 K were investigated.
