Description

technical field [0001] The present application relates to the technical field of material mechanical property measurement, in particular to a magnetron sputtering forming device for testing the mechanical properties of mesoscale tensile specimens. Background technique [0002] On the mesoscopic scale, when the number of grains in the thickness direction of the metal sheet decreases to a critical value, for example, for a pure copper sheet, the value is ~4, the plastic deformation ability of the metal sheet will decrease rapidly, and the size effect will appear. a phenomenon. By means of normal loading, pressure is applied to the thickness direction of the sample. During the deformation process, the sample is not only subjected to the tensile stress in the length direction of the sample, but also the compressive stress perpendicular to the surface of the sample, which is conducive to healing. The micro-cracks of the material during the deformation process can improve its pla...
