Application field and importance of metallographic microscope
The application fields and importance of metallographic microscope are mainly reflected in the following aspects.
1 material selection: there is a certain correspondence between the microstructure and properties of materials, and appropriate materials can be selected accordingly.
2 check: raw material check and process check.
3 sampling inspection: metallographic examination of semi-finished products is carried out in the product manufacturing process to ensure that the microstructure of products meets the processing requirements of the next working procedure.
Process evaluation: to judge and identify the product process.
5. In-service evaluation: provide basis for the reliability, reliability and service life of in-service parts.
Failure analysis: the defects of technology and material are found, thus providing macro and micro analysis basis for the analysis of failure reasons.
7 Research means: It provides an important basis for adjusting the research direction and technology.
Metallographic action
Study on heat treatment technology of steel: the principle of heat treatment of steel is based on the phase transformation of steel during heating and cooling, and metallographic technology is an important experimental means for phase transformation research.
Development of shape memory alloy: Shape memory alloy was also discovered by metallographic analysis.
Quality control of products: every link in the production process of products, from the acceptance of raw materials, the control of processing technology, to the quality evaluation of semi-finished products and finished products.
Failure analysis: it is difficult to completely avoid the failure of mechanical equipment and parts in the form of deformation, fracture wear and corrosion, and use metallographic examination to find out the reasons and prevent them.
5 accident analysis: application and analysis and proof of fire accidents have good repeatability, comparability and intuition in the field of fire cause identification.
Application field of metallographic microscope
Metallographic examination of ferrous metals, nonferrous metals, powder metallurgy, identification and evaluation of the structure after surface treatment of materials.
