A clad material is a laminate having combined properties of strength, workability, corrosion resistance, economical efficiency, and so forth. However, a clad material is difficult to form by rolling, due to the different mechanical properties of the materials. The aim of the present research is, with regard to a double-layered clad material, to investigate the characteristics of rolling deformation by means of rolling the clad material models made of plasticine, in order to seek the most appropriate, clad-rolling conditions. In this paper are explored: the manufacturing of plasticine with its mechanical properties modified by the addition of chemical additives, in order to expand the differences in strength; the validity of these plasticine models; and experimental rolling-test results with plasticine models.
