The phase field models have been built to study the influence of the nonuniform grain boundary energy for abnormal growth of grains in the AZ31 magnesium alloy in the real time and space. The simulated results show that if the grains of a certain orientation with low grain boundary energy in the AZ31 Mg alloy, abnormal grain growth will occur after annealing treatment, and only if the local low grain boundary energy is less than 0.98σ0, can the certain grains grow abnormally in the microstructure.

“…The other elements cannot significantly improve the magnetostriction. On the other hand, in order to enhance the mechanical properties, great efforts has been made by adding alloying elements such as B, C, Al, V, Cr, Mo, Mn, Nb [9][10][11][12]17,32] or carbide precipitates such as X-C (X = Zr, Nb, Mo, Ta) [33][34][35][36][37] . This method is effective to enhance the mechanical properties, but it cannot significantly improve the magnetostrictive performance.…”

M agnetostriction is generally considered as the change in dimension of materials under an applied external magnetic field. Magnetostrictive materials have attracted widespread attention due to their utilization in actuators, sensors, transducers, microelectromechanical systems and energy harvesting [1,2] . Among various magnetostrictive materials, the Tb-Dy-Fe alloys (known as Terfenol-D) and Fe-Ga alloys (known as Galfenol) are the two most promising materials. Compared to Terfenol-D, Fe-Ga alloys exhibit good combination advantages: (i) low saturation magnetic field (~100 Oe); (ii) moderate magnetostriction (~400 ppm); (iii) good mechanical properties; (iv) low cost; (v) high Curie temperature (T c >650 °C ) [3][4][5][6][7] . Therefore, since 2000, many studies on microstructure, magnetostrictive and mechanical properties of Fe-Ga alloys have been carried out.Fe-Ga single crystal alloys exhibit good robustness,
