Abstract: The effect of temperature and tensile force on the threshold deformation and the thickness ratio after bond was mainly studied under the condition of control atmosphere rolling process. The results show that applying front and rear tensile force will decrease the threshold deformation obviously, which will weaken with increasing temperature. While the control of tensile force will adjust the thickness ratio within a small extent.
Key words: laminated materials; tensile force; threshold deformation; thickness ratio; control atmosphere rolling
