Abstract : Tensile specimens in the thickness range 3.76 microns to 1.02 mm., prepared from thin rolled type 304 stainless steel foils, and recrystallized to a lateral grain size approximately 15 to 30 microns were strained to fracture in an Instron testing machine at an elongation rate of 0.000833 mm./sec. in order to experimentally determine the effect of foil thickness on mechanical behavior in tension. Fracture surfaces of broken samples were subsequently examined by scanning electron microscopy in order to observe transverse foil necking, and characterize the fracture mode. To the extent that at thickness down to 3.76 microns foils retain moderate ductility and voids are detected on fracture surfaces, the mechanical behavior and fracture characteristics of thin rolled foils more closely resemble those of bulk materials than thin films of vapor deposited or electrodeposited metals.
