A Method for the Determination of Ductility for Thin Metallic Materials

Source

A method to determine the ductility of metallic foils, coatings, and films, either unsupported or as a layer in a thin composite with some carrier substrate, is described. The technique is based on a novel use of low-cycle fatigue concepts together with a fatigue ductility flex tester which subjects specimens to cyclic bending over mandrels to precisely controlled strains. This method yields the fatigue ductility which closely correlates to the true tensile fracture ductility. The technique is also useful for generic specifications, accelerated testing, and process parameter evaluations.
