In-situ liquid environment mechanics test platform of transmission electron microscope

Abstract

The invention relates to the field of raw material in-situ micro-nano experiment platforms and provides an in-situ liquid environment mechanics test platform of a transmission electron microscope. Thein-situ liquid environment mechanics test platform comprises a sample rod and a loading platform, wherein the loading platform comprises a lower chip, an upper chip and a loading device; a first groove is formed in the upper surface of the lower chip; a groove is formed in the bottom surface of the first groove; a lower film window and two through holes are formed in the bottom surface of the groove; a second groove and an upper film window are formed in the lower surface of the upper chip; the second groove and the first groove are used for forming a receiving space for mounting the loadingdevice; a thermal resistor is arranged on the upper surface of the upper chip; the lower surface of the upper chip is connected with the upper surface of the lower chip; the lower surface of the loading device is connected with the bottom surface of the first groove; a driving beam is arranged on the loading device; a sample loading area is arranged in the driving beam; the lower film window, thesample loading area and the upper film window are centered. The in-situ liquid environment mechanics test platform can achieve mechanics test of samples in the liquid corrosion environment; the problem that the transmission electron microscope is incapable of effectively carrying out in-situ mechanics test in the liquid environment at present is solved.

Description

technical field [0001] The invention relates to the field of in-situ micro-nano experimental platforms for materials, in particular to an in-situ liquid environment mechanics test platform for transmission electron microscopy. Background technique [0002] Transmission Electron Microscope (TEM), referred to as TEM, is a modern large-scale instrument for studying the microstructure of matter, and is widely used in the fields of physics, chemistry, material science and life science. The traditional transmission electron microscope characterization technology realizes the characterization and analysis of the microstructure, chemical composition and defects of materials through bright field images, dark field images, electron diffraction, X-ray energy spectroscopy, and electron energy loss spectroscopy. [0003] The macroscopic mechanical properties of a material (such as strength, hardness, plasticity, and toughness, etc.) are closely related to its microstructure, that is, the...
