To composite alloy plate greatly, shortcoming is complex process, and the thickness and thickness of product are relatively difficult to control.
Cold rolling is compound including production technology that " surface treatment one room temperature under the compound diffusion annealing of cold rolling " is main process.
Compared with method hot rolling method, the first pass deformation of cold rolling compound tense wants bigger, generally to reach 60-70%, even more high, but
Cold rolling composite algorithm can realize the combination of a variety of constituent elements, and can produce coiled composite, and accurate size is efficient, therefore is
One of current most widely used method.Although cold rolling composite algorithm early in the fifties i.e. have been used for industrial production, for copper/
But preferable effect is not obtained during the production of steel composite material, the reason is that the matrix and oxide of copper and its alloy are all with good
Good plasticity cold rolling compound tense, though blank reaches 70% its surface and does not also split through brushing and first pass deformation
Mouthful, the result is that blank is squeezed into the breach of steel and compound (the further first passage of increase of steel with initial surface with thin oxide-film
Deflection is limited again be subject to mill capacity), therefore combination is very fragile, bond strength is low and unstable.
