Abstract

With the miniaturization of feature size, size effect is the main problem in micro forming process and material behavior. In the paper, the size effect of foil thickness on deformation behavior and fracture was investigated by using uniaxial tensile test of 316L stainless steel sheet. The tensile fracture morphology was studied by scanning electron microscopy, and the fracture mechanism of samples with different thicknesses was discussed. The results show that when the thickness of sample is reduced to 0.1mm, the yield strength increases significantly and the elongation decreases significantly. The fracture of 2mm thickness sample is similar to that of cup cone. The fracture of 1mm and 0.6mm thickness sample is serrated, and the fracture of 0.1mm thickness sample is uniform
