The role of metallographic microscopes in scientific research and business
The rapid development of industrial production and science and technology has enabled metal materials to be widely used. This is because metal materials have excellent mechanical properties (strength, hardness, plasticity), physical properties (electrical conductivity, thermal conductivity, magnetic conductivity, etc.), chemical properties (corrosion resistance, oxidation resistance, etc.) and process properties (castability, weldability, Hot and cold processing, etc.). With the widespread application of atomic energy technology, rocket technology, jet technology, aerospace technology, navigation technology, chemistry, radio and other technologies, the requirements for various properties of metal materials are higher. Metals and alloys are often required to have high seismic strength and high temperature resistance. And low temperature resistance, thermal shock resistance, elastic modulus does not change with temperature, etc. These properties are closely related to the metallographic structure of the material.
A long time ago, people have used various methods to study the intrinsic relationship between the properties, properties and structures of metals and alloys in order to find ways to ensure the quality of metal and alloy materials and create new alloys. However, only after the advent of the microscope, Only then do people have the conditions for in-depth research on metal materials. Under a microscope that magnifies hundreds of times or even tens of thousands of times, we observe the internal structure of metal materials, that is, the metallographic structure, and discover the close relationship between the macroscopic properties of metals and the morphology of the metallographic structure, making the metallographic structure analysis method the most basic , one of the most important and widely used research methods. Therefore, in any machinery manufacturing, metallurgical enterprises and corresponding research institutions, science and engineering colleges, etc., there are metallographic inspection rooms or metallographic research rooms, which use various metallographic microscopes to conduct a large number of complex and delicate tasks. Metallographic structure research work.
Metallographic microscopes are the eyes of industrial production such as metallurgy, machinery manufacturing and transportation, and play an important role in preventing waste products and improving product quality. It is used in industrial production to check the smelting and rolling quality of metals, control the heat treatment process, help improve the heat treatment process operation, improve the quality of workpieces, study the existence of non-metallic inclusions in metal materials, and observe the shape, size, and shape of inclusions. Distribution and quantity, measure the optical properties of inclusions, thereby judging the type of inclusions, and evaluate the grade of the material accordingly. Use high-power metallographic microscopes to study the fractures of metal parts. You can judge the size of grains based on the shape of the fractures and analyze machinery. The reason for the damage is that the use of high-temperature metallographic microscopes can also help people study the rules of organizational transformation, track the transformation process, and continuously observe the organizational transformation of metals or alloys within a certain temperature range. Therefore, metallographic microscopes are widely used in steel smelting, boiler manufacturing, mining, machine tools, tools, automobiles, shipbuilding, bearings, diesel engines, agricultural machinery and other industrial sectors. They have become optical instruments widely used in industrial production, national defense engineering and scientific research.
