The application fields and importance of metallographic microscopes are mainly reflected in the following aspects:
1 Material selection: There is a certain correspondence between the microstructure and performance of the material, based on which the appropriate material can be selected.
2 Verification: Raw material verification and process verification
3 Sampling inspection: The product manufacturing process conducts metallographic inspection on semi-finished products to ensure that the microstructure of the product meets the processing requirements of the next process.
4 Process evaluation: Judge and identify the qualification of the product process.
5 In-service evaluation: Provide a basis for the safety, reliability and in-service life of in-service parts.
6 Failure analysis: Discover processability and material defects, thereby providing macroscopic and microscopic analysis basis for the analysis of failure causes.
7 Research methods: Provide an important basis for adjusting research directions and processes.
Role of metallography
1 Research on steel heat treatment process: The principle of steel heat treatment is based on the phase change of steel during heating and cooling, and metallographic technology is an important experimental means of phase change research.
2 Development of shape memory alloys: Shape memory alloys are also discovered through metallographic analysis.
3 Product quality control: every link in the production process, from the acceptance of raw materials, control of processing technology, to the evaluation of the quality of semi-finished and finished products.
4 Failure analysis: It is difficult to completely avoid failures in the form of deformation, fracture, wear and corrosion during the use of mechanical equipment and parts. Metallographic inspection is used to find out the causes and prevent them.
5 Accident analysis: Application and analysis and evidence of fire accidents in the field of fire cause identification have good repeatability, good comparability and strong intuitiveness.
Application fields of metallographic microscope
Metallographic inspection of ferrous metals, metallographic inspection of non-ferrous metals, metallographic inspection of powder metallurgy, identification and evaluation of tissues after material surface treatment.
