Effect of Static Magnetic Field on Nucleation and Growth Orientation of Fe Atomic

In this paper,the effect of static magnetic field on nucleation and growth orientation of Fe atomic was researched from the perspective of crystal structure by the edge-edge matching model and electron backscatter diffraction（EBSD）technique.It is found out that the optimal orientation relation between Fe_xO and Fe is[010]//[110]＆（200）//（110） independent on magnetic field.during the conversion of Fe_xO→Fe,and Fe_xO preferentially precipitates α-Fe crystal nucleus on {100} crystal plane both under the action of magnetic field and conventional metallurgical conditions.A constant magnetic field（B=1 T） does not change the nucleation position of α-Fe on the wustite surface,but it has an impact on the growth orientation of α-Fe,causing it to deflect gradually from the preferential ＜100＞ direction to ＜100＞,＜101＞ and ＜111＞ directions.
