Application Areas and Importance of the Metallurgical Microscope
The application fields and importance of metallurgical microscopes are mainly reflected in the following aspects:
① Material Selection: There is a certain correlation between the microstructure and properties of materials, based on which suitable materials can be selected.
② Verification: Raw material verification and process verification.
③ Sampling Inspection: Metallographic inspection of semi-finished products during the product manufacturing process to ensure that the microstructure of products meets the processing requirements of subsequent working procedures.
④ Process Evaluation: To judge and verify the qualification of product manufacturing processes.
⑤ In-service Assessment: To provide a basis for the safety, reliability and service life of in-service components.
⑥ Failure Analysis: Detect process-related and material-related defects, so as to provide macroscopic and microscopic analytical evidence for failure cause analysis.
⑦ Research Tool: Provide important basis for adjusting research directions and manufacturing processes.
Functions of Metallography
① Research on Heat Treatment Processes of Steel: The principle of steel heat treatment is based on the phase transformation of steel during heating and cooling, and metallographic technology serves as a vital experimental tool for phase transformation research.
② Development of Shape Memory Alloys: Shape memory alloys were discovered by means of metallographic analysis.
③ Product Quality Control: Every link in product production, from raw material acceptance and processing control, to quality evaluation of semi-finished and finished products.
④ Failure Analysis: Deformation, fracture, wear, corrosion and other forms of failure are hardly avoidable for mechanical equipment and components in service. Metallographic examination is used to identify failure causes and implement preventive measures.
⑤ Accident Analysis: Applied in fire incident analysis and evidence collection for fire cause identification. It features good repeatability, favorable comparability and high intuitiveness.
