摘要
对爆炸复合的钛/钢复合板进行了一道次60%的温轧,研究了一道次温轧钛/钢爆炸复合板的近界面微观组织及剪切强度。结果显示,一道次温轧工艺可以引起钛层和钢层近界面组织的显著剪切变形。由于剪切变形,钛层形成了RD分散织构。钢层含有高组份的旋转立方织构及低组份的γ纤维织构。对比常规多道次轧制方法,由于剪切变形可细化界面化合物,使得一道次温轧钛/钢复合板抗剪切强度得到提升。
Explosively welded Ti/steel clad plates were one-pass warm rolled by 60%,microstructures of the Ti layer and steel layer adjacent to interface were investigated,and shear strength of the one-pass warm rolled clad plates was tested.Results show that the one-pass warm rolling process can cause obvious shear deformation in both the Ti layer and steel layer adjacent to the interface.Because of the shear deformation,the RD-split basal texture forms in the Ti layer.In the steel layer,high fraction of the rotated cube texture and low fraction of theγfiber texture form.Compared with the common multi-pass rolling method,shear strength of the onepass warm rolled Ti/steel clad plate is improved because the shear deformation refines the interfacial compounds.
