Conclusions1。铝合金的挤压棒具有复杂的纤维结构，通常与工件的横截面形状无关。完全轴向织构只在挤压棒的轴线附近出现。随着离轴距离的增加，轴向织构逐渐减弱，<111>和<100>织构保持不变。滚动织构（110）[112]在未来大晶体边缘的区域占主导地位。轴向纹理分量<100<形成一个紧致区域，其形状随距杆轴线的距离而变化，并与给定截面的变形类型相匹配。通过截面的纹理变化是由杆的不同截面的变形类型的差异决定的。随着纵向伸长率的增加，出现了：a)中心截面对称变窄；B)中间区截面不对称变窄；C)未来边缘外区径向变窄，切向微伸长。
Conclusions1.Extruded rods of aluminum alloys have a complex fibrous structure that is generally independent of the shape of the cross section of the piece.2.A completely axial texture is found only near the axis of extruded rods. With increasing distance from the axis the axial texture diminishes and the <111> and <100> texture is retained. The rolling texture (110) [112] predominates in the area of the future rim of large crystals.3.The axial texture component <100< forms a compact region whose shape varies with the distance from the axis of the rod and matches the type of deformation in the given section.4.The variation of the texture through the section is determined by the difference in the type of deformation in the different sections of the rod. With elongation in the lengthwise direction there occurs:a)symmetrical narrowing of the cross section in the center;b)unsymmetrical narrowing of the cross section in the intermediate zone;c)narrowing in the radial direction and slight elongation in the tangential direction in the outer zone of the future rim.
