How to use and understand metallographic microscopes
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 Check: Raw material check and process check
3. Sampling inspection: The product manufacturing process conducts metallographic inspection of semi-finished products to ensure that the microstructure of the product meets the processing requirements of the next process.
4 Process assessment: Judge and identify the qualification of product process.
5. In-service evaluation: Provides basis for the accuracy, reliability and service life of parts in service.
6 Failure analysis: Discover process and material defects, thereby providing macro and micro analysis basis for the analysis of failure causes.
7 Research methods: Provide important basis for adjusting research direction and technology.
Metallographic effects
1. Research on steel heat treatment process: The principle of steel heat treatment is based on the phase change of steel during the heating and cooling process, and metallographic technology is an important experimental method for phase change research.
2 Development of shape memory alloys: Shape memory alloys were also discovered through metallographic analysis.
3 Product quality control: every link in the product production process, from the acceptance of raw materials, the control of processing technology, to the quality assessment of semi-finished products and finished products, etc.
4 Failure analysis: It is difficult to completely avoid failures in the form of deformation, fracture, wear, corrosion, etc. during use of mechanical equipment and parts. Use metallographic inspection to find out the reasons and prevent them.
5 Accident analysis: Application and analysis and evidence of fire accidents in the field of fire cause identification, with good repeatability, good comparability and strong intuition.
Application areas of metallographic microscopes
Metallographic inspection of ferrous metals, metallographic inspection of non-ferrous metals, metallographic inspection of powder metallurgy, structural identification and evaluation of materials after surface treatment.
