  • MEMS system is paid more and more attention by people There are many difficulties in conventional tensile and compression experime nts for samples with sizes below 100 microns.Nanocompression exp eriment is becoming the main way to measure mechanical properties at micro/nano scale because it only generates a small pressure in the local volume of material surface.Therefore, it is necessary to conduct experimental research on material deformation behavior at micro and nano scale.In order to study the deformation behavior of single-crystal face-centered cubic materials at micro or nano scale, the authors analyzed the initial plastic deformation behavior of copper nanocry stal columns and the influence of crystal defects on the initial plastic deformation of single-crystal copper by means of nanocompression experiment. The results show that copper columns exhibit a greater de gree of elastic deformation in the process of nanocompression.At the same time, the reason and the influence of the bulge of the material s around the compression are analyzed.It is concluded that the bulge of the materials around the compression of copper nanomaterials will lead to the increase of the nanohardness and the measured elastic modulus. In order to study the influence of surface topography inho mogeneity on the initial plastic deformation behavior of copper nano rods,nano-scale surface defects were prepared on the surface of copper nanorods by heating method, and the experimental data of nano compression of surface defects were compared and analyzed. The results show that the existence of surface defects will greatly affect the initial plastic deformation of copper nanorods.The morphology of the dislocation around thecompression point of the copper nanocolumn was observed by transmission electron microscope.Besides the dislocation around the compression point, the coexistence of layered dislocation, partial dislocation and dislocation ring was also observed.The results show that the initial plastic deformation of the copper nano column is closely related to the occurrence of dislocation.
