摘　　要：为了提高钛-钢复合板界面结合强度,本文提出在钛-钢之间加入Ni箔作为过渡层,采用真空轧制方法制备TA1-Ni-Q235复合板,研究了Ni中间层厚度及轧制温度对复合板组织及结合强度的影响。实验结果表明,Ni中间层可有效阻止Ti-Fe和TiC化合物生成,随着Ni中间层厚度增加,阻止C元素扩散作用加强,界面结合强度提高;随着轧制压下率的增加,界面结合强度提高;随着轧制温度的提高,界面化合物层厚度增加,界面结合强度下降,其中,Ti-Ni界面处形成Ti2Ni和TiNi化合物。In order to increase the Ti-steel clad plate bonding strength,a Ni foil is proposed to be added between titanium and steel as a transition layer.The TA1-Ni-Q235 steel clad plate was prepared by hot rolling after raw slabs stacking and vacuuming.The effect of Ni interlayer thickness and rolling temperature on microstructure and bonding strength were studied in clad plate.The results show that the addition of Ni interlayer can suppress the generation of brittle compound Ti-Fe and TiC at the interface of TA1-steel during the rolling process.As the thickness of the Ni intermediate layer increases,the effect of inhibiting brittle compounds significantly enhances and the interfacial bonding strength increases.Moreover,the interfacial bonding strength increases with increase of rolling reduction rate.The interfacial bonding strength decreases with the rise of rolling temperature.The Ti2Ni and TiNi compounds form at the Ti-Ni interface.
