Abstract The present work aimed to comparatively analyze microstructure and magnetostriction of Fe, and Fe₈₃Ga₁₇ and Fe₈₃-Ga₁₇Pr_0.3 magnetostrictive alloys. We successfully prepared the alloys by employing a non-consumable vacuum arc melting furnace and applying a protective argon atmosphere, and observed crystal structures and surface morphologies of the alloys via X-ray diffraction (XRD), optical microscopy (OM) and scanning electron microscopy (SEM) combined with energy dispersive spectroscopy (EDS), respectively. The magnetostriction coefficients of the alloys were measured by means of resistance strain method. The results indicated that Fe and Fe₈₃Ga₁₇ alloy consist of a single phase of A2 with bcc structure, while the Fe₈₃Ga₁₇Pr_0.3 alloy is composed of A2 phase and a small amount of Pr-rich phase. The Pr doping into Fe₈₃Ga₁₇ alloy facilitates the preferred growth in (100) orientation of A2 phase in the alloy. The microstructures of the Fe, Fe₈₃Ga₁₇ and Fe₈₃Ga₁₇Pr_0.3 alloys present anisometric morphology with strip-like grains, the equiaxial morphology with coarse grains and a columnar structure with fine grains, respectively. The magnetostriction coefficient of Fe is negative, whereas the magnetostriction coefficients of Fe₈₃Ga₁₇ and Fe₈₃Ga₁₇Pr_0.3 alloys are positive. The magnetostrictions of three alloys can be sequenced as Fe₈₃Ga₁₇Pr_0.3>Fe₈₃Ga₁₇>Fe.
