| Abstract Scope |
Galfenol,(Fe<sub>100x</sub>-Ga<sub>x</sub>, 10≤x≤30) an iron rich alloy within the Fe-Ga system exhibits a considerable magnetostriction coefficient, making it a viable candidate for applications in sensor technology.
To improve manufacturing costs of Fe-Ga alloys, dopants such as Ce and Zr may be used to enhance the magnetostriction of polycrystalline forms of the material. Building on recent work, where a thermodynamic database for the Fe-Ga system has been established, the addition of alloying elements to improve magnetostrictive properties is investigated. In doing so a CALPHAD-type thermodynamic database is expanded to include the Fe-Ga-Ce-Zr system. Application of this database and understanding the effects of alloying elements on phase formation allows for an efficient and effective method to design new magnetostrictive materials.
