Which is the best metallurgical microscope? Functions of a metallurgical microscope

To say which brand is good, we must first clarify the selection criteria of the metallographic microscope, and consider the continuous stability of the mechanical properties of the metallographic microscope in use, which we call the continuous stability of mechanical properties. Metallurgical microscope is a high-precision optical instrument, its service life can reach more than 30 years, users should also investigate the manufacturer in the manufacture of materials, manufacturing accuracy, mechanical design of the scientific and reasonable.

The long-life microscope should be mainly made of cast iron materials in the main machine manufacturing material, and avoid using too many functional plastic materials. At the same time, in order to maintain a long service life, the optical components need to be treated with mildew, and the coating is mainly anti-mildew, so as to avoid the purchase of drugs to prevent mildew. The mechanical gear device should ensure that it does not slip down after long-term high-intensity use, and the performance is stable, and the harmonic gear is the first choice.

The above necessary conditions put forward clearer requirements for manufacturers in manufacturing from a practical point of view, and users should also follow the above principles to choose an economical metallurgical microscope.

Then compare the standard circles and lines with the actual objects in the image to find the error of the workpiece.

Metallurgical microscope scope of application:

The metallographic microscope is mainly suitable for the electronic, metallurgical, chemical and instrumentation industries to observe transparent, translucent or opaque objects, that is, objects that are illuminated by transmitted light and reflected light, such as gas springs, manifolds, printed circuit boards, liquid crystal panels, thin films, fibers, textiles, coatings and other non-metallic materials, and upright metallographic microscopes are also suitable for observation and analysis in medicine, agriculture and forestry, schools and scientific research departments.

The metallographic microscope was originally used to study and analyze the microstructure of various metal and alloy materials, the quality of castings and the phase structure after heat treatment, and it is an essential instrument for metallurgical research. Therefore, factories, laboratories, scientific research institutions, and colleges are widely used for teaching.

Other industries such as electronics, thin films, and coatings are made of cold-mounted materials and placed directly on the workbench because of the transparency of the material.

For metallographic analysis, a metallographic analysis microscope should be selected. The application of metallographic analysis microscope is becoming more and more extensive, and the use of metallographic analysis microscope and professional metallographic analysis software is a complete set of computer quantitative metallographic analysis is gradually becoming a powerful tool for people to analyze and study various materials, establish the quantitative relationship between the microstructure and various properties of materials, and study the microstructure transformation dynamics of materials.

The metallographic image analysis system can easily measure various parameters such as area percentage, average size, average spacing, aspect ratio and other parameters of features, and then determine the three-dimensional spatial shape, quantity, size and distribution of features according to these parameters, and establish an internal relationship with the mechanical properties of materials, so as to provide reliable data for more scientific evaluation of materials and rational use of materials.

Optical microscopes and metallurgical microscopes are both commonly used microscopes, but their use scenarios and principles are very different. This article will introduce the difference between an optical microscope and a metallographic microscope.

1.Principle.

The principle of an optical microscope is based on optical physics, which uses an optical lens to magnify the image of a sample. A light source is placed on the sample, and the light passes through the sample and is focused onto the lens to form a magnified image. By adjusting the position of the lens, the sample can be clearly magnified and observed.

The principle of metallurgical microscopy is based on metallurgical microscopy, which uses the preparation of metallographic specimens and the microstructure of metals. After the metallographic specimen is prepared on the surface of the sample, the crystal structure and microstructure of the metal can be observed by metallographic microscopy, using different microscope lenses.

2.Apply.

Optical microscopy is widely used in laboratory research in some physicochemical and biological fields, such as the observation of cells, bacteria, and tissues. Due to the characteristics of high resolution, clear imaging, and observation of surface fine structures, optical microscopes have been widely used in practical applications.

Metallurgical microscopy is mainly used in the preparation and microstructure study of metal and alloy materials in materials science. For example, in the preparation process of machining, heat treatment and welding, the microstructure of metal materials can be observed using a metallographic microscope to understand the changes in their properties and microstructure. In addition, metallurgical microscopes can be used for quality control and process optimization of materials to improve the performance and functionality of materials.

3.Resolution.

The resolution of the light microscope is slowly around the left and right, and most cells and bacteria can be observed. Metallurgical microscopes, on the other hand, have a resolution range that allows them to observe the microstructure and grain size of many metallic and alloying materials.

4.Applicable sample type.

Optical microscopy is suitable for transparent or thin samples, such as biological tissues, chemical crystals, microprocessing chips, etc. The metallurgical microscope is suitable for metal and alloy materials, and it can obtain the microstructure information of metal and alloy materials through the preparation of metallographic samples.

5.Microscopy imaging methods.

Optical microscopy images are done by magnifying the sample image through a lens to form a clear magnified image. The imaging method of metallurgical microscope uses metallurgical microscopy to process the sample, and uses different metallurgical microscope lenses to observe and photograph according to the crystal structure and tissue morphology of the metal.

Conclusion In general, optical microscope is generally used in the fields of physics, chemistry, and biological sciences to directly observe and study the structure and characteristics of substances such as cells, tissues, and crystals, while metallurgical microscope is mainly used in the field of materials science to observe the microstructure and grain size of metal materials. Although there are differences between the two microscopes, both can provide strong technical support for research in different fields.
