Overview

The transmission electron microscopy (TEM) force electric in-situ system uses MEMS chips to construct a force electric composite multi field automatic control and feedback measurement system in the in-situ sample stage. Combined with various modes such as EDS, EELS, SAED, HRTEM, STEM, etc., it realizes real-time and dynamic monitoring of key information such as microstructure, phase transition, elemental valence state, micro stress, and structural and compositional evolution at the surface/interface of the sample under vacuum environment with changes in electric field and applied force at the nanoscale.

In situ mechanical compression process of tungsten nanocolumns

During the elastic deformation process of tungsten nanowires under stress, the strength and plasticity of the elastic and plastic deformation processes are key characteristics of the application of structural materials. Dislocations play an important role in regulating the strength and plasticity of materials. Generally speaking, the harder dislocation slip, the stronger the material, and the second phase is often used to hinder dislocation movement to improve material strength. For example, ceramic phases can be used for metal reinforcement because the significant difference in elastic modulus and severe interface mismatch between the matrix and the second phase can enhance the metal material. Unfortunately, the hard second phase generally achieves the strengthening effect at the expense of ductility. In addition, severe dislocation accumulation at the interface may lead to local stress concentration, resulting in sudden failure of the material during service. Essentially, it requires both a second phase to prevent the movement of dislocations and a certain degree of compatibility with the plasticity of dislocation slip. Through in-situ mechanical testing, it is more convenient to study the changes in the strain field at the material interface in order to optimize the strength and plasticity of composite materials.
