借助于 ＥＢＳＤ方法，研究了 ８个位向 Ｂ２结构 Ｆｅ３Ａｌ单晶室温拉伸变形时晶体取向的转动结果表明，无论原始取向如何，在拉伸过程中晶体拉伸轴总会向着（１１０）方向转动，也即（１１０）为稳定取向．当晶体拉伸轴转向取向三角形中部的软取向时，晶体表现为几何软化，相应的加工硬化率较低反之，当晶体拉伸轴转向（００１）－（１０１）对称线时，晶体表现为几何硬化，相应的加工硬化率较高．当拉伸轴处于软取向时，单晶试样的板面转向（１１１），而当拉伸轴处于硬取向时，板面转向（１１０）．晶体拉伸轴向（１１０）的转动与多晶 Ｆｅ３Ａｌ基合金｛００１｝（１１０）织构相对应；板面向（１１１）的转动与｛１１１｝织构对应；板面向（１１０）的转动则对应｛１１０｝（００１）的剪切织构．
By means of EBSD method, the results of the crystal orientation rotation at room temperature tensile deformation of 8-position B2 Fe3Al single crystal show that the crystal stretching axis always rotates in the direction of (110) regardless of the original orientation during the stretching process , Ie (110) is a stable orientation. When the crystal axis is oriented towards the soft orientation in the middle of the oriented triangle, the crystal behaves as a geometric softening with a correspondingly lower work hardening rate. Conversely, when the crystal axis is oriented to the (001) - (101) symmetry line, the crystal behaves as a geometry Hardening, the corresponding high rate of work hardening. When the tensile axis is in soft orientation, the face of the single crystal sample is steered (111) and the plate is steered (110) when the tensile axis is in hard orientation. The rotation of the crystal in the axial direction (110) corresponds to the {001} (110) texture of the polycrystalline Fe3Al-based alloy; the rotation of the plate in the direction of (111) corresponds to the texture of {111}; the rotation of the plate in the direction of Shear texture corresponding to {110} (001).
