Application of metallographic microscope in metal machinery industry
The application fields and importance of metallography mainly include the following aspects:
1 Can be used to check raw materials and processes
2 Metallographic inspection of semi-finished products can be carried out during the product manufacturing process to ensure that the microstructure of the product meets the processing requirements of the next process.
3. There is a certain correspondence between the microstructure and performance of materials, based on which appropriate materials can be selected.
4 Provide a basis for the accuracy, reliability and service life of parts in service.
5. Judge and identify the qualification of product process.
6. Discover process and material defects, thereby providing macro and micro analysis basis for the analysis of failure causes.
7 Provide important basis for adjusting research direction and technology.
Metallographic effects
1 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.
2. 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.
3. Development of shape memory alloys: Shape memory alloys were also discovered through metallographic analysis.
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.
