本文介绍了1441铝锂合金板材织构的研究结果。疲劳裂纹扩展试验过程中的断口形貌形成的纹理不均匀性的依赖的特殊性被认为是。中心缺口试样的疲劳裂纹偏离主方向可能与{110）（112）织构的出现有关。晶体学刻面断裂表面的形成是由于裂纹尖端之前的滑移沿着相等剪切应力的111（110）滑移系而延伸的裂纹。
Results of texture investigations in sheet and plate ofthe A1-Li alloy 1441 are presented. The peculiarities of fracture surface morphology formation during fatigue crack propagation tests in dependence on texture inhomogeneity are considered. The deviation ofthe fatigue crack from the principal direction in center-notched specimens could be related to occurrence of a {110)(112) texture. The formation of crystallographic faceted fracture surfaces results from cracks extending by slip along equally shear stressed 111 (110) slip systems ahead of the crack tip.
