Application areas and importance of metallurgical microscopy
The application fields and importance of metallurgical microscope are mainly reflected in the following aspects: 1 Selection of materials: there is a certain correspondence between the microstructure and properties of materials.
1 Selection of materials: there is a certain correspondence between the microstructure and properties of the material, according to which the appropriate material can be selected.
2 Calibration: raw material calibration and process calibration
3 Sampling: the product manufacturing process of semi-finished products for metallurgical inspection to ensure that the microstructure of the product to meet the processing requirements of the next process.
4 Process Evaluation: Judge and identify the qualification of product process.
5 In-service evaluation: in-service parts **, reliability and parts in service to provide a basis for life.
6 Failure Analysis: Discover process and material defects, so as to provide macro and micro analysis basis for the analysis of the cause of failure.
7 research tools: to adjust the direction of research and technology to provide an important basis.
Metallography role
1 steel heat treatment process research: the principle of heat treatment of steel is based on the steel in the heating and cooling process of phase change, metallographic technology is an important experimental means of phase change research.
2 The development of shape memory alloy: shape memory alloy is also found through metallographic analysis.
3 Quality control of products: every link in the production process of products, from the acceptance of raw materials, the control of processing technology, until the evaluation of the quality of semi-finished products and finished products.
4 Failure analysis: mechanical equipment and parts in the use of the process is difficult to completely avoid deformation, fracture wear and corrosion and other forms of failure, the use of metallurgical examination to find out the reasons, and to prevent.
5 accident analysis: application and fire accident analysis and proof in the field of fire cause identification, with good repeatability, comparability and intuition.
Application fields of metallographic microscope
Ferrous metal metallographic examination, non-ferrous metal metallographic examination, powder metallurgy metallographic examination, material surface treatment organization identification and evaluation.
