Press-formability of stainless steel and aluminum clad sheet

摘要: Abstract This paper deals with a stainless steel and aluminum clad sheet produced by pressure welded hot rolled sheets. The tensile tests made on the as well elements which compose it, sheets, were carried out in order to determine fundamental mechanical properties. Basic press-forming tests, include punch stretching deep-drawing, done. characteristics of joining process within range uniform elongation shows that portion has higher ductility than steel. However, latter local deformation larger Lankford, r, owing inherent characteristic two materials. formability processes both are when is set outer side cup. factors related deformation, such wrinkling cup height controlled due its high strength. fracture mechanisms clarified detailed measurements thickness strain.
