The role of high power microscope in industrial development

The rapid development of industrial production and science and technology has made metal materials widely used. This is because metal materials have excellent mechanical properties (strength, hard skin, plasticity), physical properties (electrical conductivity, thermal conductivity, permeability, etc.), chemical properties (corrosion resistance, oxidation resistance, etc.) and processing properties (Castability), weldability). Hot and cold processing, etc.). With the wide application of nuclear technology, rocket technology, jet technology, aerospace technology, navigation technology, chemistry and radio technology, etc., metal materials are required to have various characteristics, and metals and alloys are required to have high seismic strength and high tensile strength . High temperature and low temperature resistance, thermal shock resistance and the elasticity of chess will not change with temperature. These properties are closely related to the metallographic structure of the material.

A long time ago, people used various methods to study the intrinsic relationship between the properties and properties of metals and alloys in order to find ways to ensure the quality of metals and alloy materials and to make new alloys, but only under the microscope was introduced. People have the conditions to conduct in-depth research on metal materials. Under a microscope of hundreds or even tens of thousands of times, the internal structure of metal materials, that is, the metallographic structure, is observed, and the close relationship between the macroscopic properties of the metal and the metallographic structure is observed, which makes the metallographic structure split method the basis , Important, one of the widely used research methods. Therefore, there are no metallographic laboratories or metallographic laboratories in any machinery manufacturing, metallurgical enterprises and their corresponding research institutions, polytechnics and universities, but various metallographic microscopes are used to conduct a large number of complex and fine metal structures. research work.
