Abstract:

The influences of the metal component and its thickness ratio on the mechanical and deep drawing pro- perties of the stainless steel/aluminum/stainless steel-laminated sheet were investigated based on the uniaxial ten- sile and swift cup tests.The results show that (1) the mechanical and deep drawing properties of the laminated sheet come from an interplay of three kinds of metal components rather than a simple superposition of the perform- ance of each component; (2) the mechanical and deep drawing properties of the laminated sheet are much closer to those of the components of the best properties; (3) the mechanical and deep drawing properties of the laminated sheet increase with the thickness ratio of the component of higher tensile stress; (4) as the strain-hardening index and the tensile strength of the component increase,the mechanical and deep drawing properties of the laminated sheet both tend to become better; and (5) the laminated sheet possesses a better deep drawing property when the component of higher tensile strength contacts with the die during deep drawing.

Key words: stainless steel/aluminum/stainless steel, laminated sheet, mechanical property, deep drawing pro- perty
