摘 要: 通過異步軋制， 研究了高純鋁箔冷軋織構(gòu)沿板厚的分布規(guī)律。 在異步軋制下， 快、 慢速輥側(cè)之間的各中間層的織構(gòu)類型不同。 速比為1.28， 形變量為99.2%時(shí)， 隨厚度的增加， 呈現(xiàn)出極有規(guī)律的變化: ｛100｝絲織構(gòu)含量近線性減少， 而｛112｝， ｛102｝， ｛123｝絲織構(gòu)含量近線性增加。當(dāng)形變量為99.2%時(shí)， 在不同速比下{001}絲織構(gòu)含量沿厚度變化趨勢不同: 速比1.28時(shí)， 呈現(xiàn)出近線性遞減； 速比1.17和1.06時(shí)， 總的趨勢也是遞減， 且在厚度d＝0.04mm處有最小值。

Abstract:Textures distribution along the thickness after cross shear rolling of high purity aluminum foils was investigated. The results show that large difference of cold rolling textures exists in the intermediate layer between the slow roller side and the fast roller. For the speed ratio 1.28 and deformation 99.2%, with increase of thickness, the volume fraction of {100} fiber shows the nearlinear decrease, however, the volume fraction of {112}, {102}, {123} fibers takes the near-linear increase. For the deformation 99.2%, there exist different tendency of change for the volume fraction of {001} fiber through the thickness at different speed ratios. For the speed ratio 1.28, the change of volume fraction of {001} fiber with the thickness presents near-linear decrease. For the speed ratio for 1.17, 1.06, the total tendency is also near-linear decrease. The relatively strong volume fraction of {001} fiber exists between the slow side surface and the fast side surface, and the minimum is formed at the thickness .d＝0.04mm side.
