Effects of Hot-rolling Temperature on Mechanical Properties and Electrical Conductivity of 1060/6201/1060 Composite Plates
1060/6201/1060 three-layer composite plates were successfully prepared by the first-pass large deformation hot rolling and the subsequent two-pass cold rolling.The effects of various hot-rolling temperatures on the mechanical properties and electrical conductivity of the composite plate were investigated in detail.The results show that the mechanical properties of the composite plates gradually decrease,and the electrical conductivity first increases and then decreases with the increase of the hot rolling temperature.After hot-rolling at 200 ℃,the tensile strength of the composite plate is 257.21 MPa,the electrical conductivity is 57.45％IACS,a best comprehensive property is obtained.During rolling at 300 ℃ and 400 ℃,the strength of the composite plate decreases,the elongation increases and the electrical conductivity increases due to dynamic recovery,coarsening of the precipitates,and the growth of matrix grains.
