The Fe-Ga alloy, a novel magnetostrictive material, distinguishes itself with a low driving magnetic field and remarkable magnetostrictive performance. As an alloy, it has garnered significant attention from researchers in solid-state physics and materials science due to its cost-effectiveness, superior mechanical properties, and high stability. These advantages make it particularly appealing for applications in micro-displacement devices, vibrators, and sensor technologies. The magnetostrictive characteristics of Fe-Ga alloys are influenced by various factors, including material texture orientation, magnetic domain distribution, alloying element additions, and, most importantly, the alloy’s phase structure. This paper provides an in-depth exploration of the phase structure of Fe-Ga alloy and comprehensively summarizes the impacts of various preparation methods on enhancing the preferred grain orientation 〈100〉. It further examines the effects of specific external magnetic fields and prestresses on altering the distribution of magnetic domains, as well as the influence of incorporating rare earth elements on improving magnetostrictive performance. Additionally, the article introduces recent research advancements regarding the influence of heat treatment on phase structure transformation and nanoprecipitate phase precipitation on the magnetostrictive properties of Fe-Ga alloys,contributing to advancing the understanding, promotion, and application of Fe-Ga alloy in the field of structure-function integrated precision device manufacturing.
