Description

technical field [0001] The invention belongs to the field of micro-nano-scale materials, and relates to a micro-nano-scale material with excellent mechanical properties and a preparation method thereof. Background technique [0002] Micro-nanoscale materials are an important part of micro-nano electromechanical systems. In order to ensure the normal service of micro-nano electromechanical systems, micro-nano-scale materials need to have excellent comprehensive mechanical properties. However, compared with macroscopic bulk materials, micro-nanoscale materials are unstable in deformation and basically have no work hardening ability. Therefore, it is of great significance to design micro- and nanoscale materials with excellent comprehensive mechanical properties. [0003] Uchic et al. pioneered the testing technology for the mechanical properties of materials at the micro-nano scale. They performed compression experiments on micron-sized nickel and found that the material sh...
