Applications of Metallurgical Microscopes in the Metal and Machinery Industry
① It can be used for the verification of raw materials and processes.
② Metallographic inspection of semi-finished products can be carried out during product manufacturing to ensure that the microstructure of products meets the processing requirements of the subsequent working procedure.
③ There is a certain correlation between the microstructure and properties of materials, based on which suitable materials can be selected.
④ It provides a basis for evaluating the performance, reliability and service life of parts and components.
⑤ Judge and identify the qualification of product processes.
⑥ Detect process defects and material defects, so as to provide macroscopic and microscopic analysis basis for failure cause analysis.
⑦ Provide an important basis for adjusting research directions and processes.
Functions of Metallography
① Product quality control: Every link in the product production process, from raw material acceptance and processing procedure control to quality evaluation of semi-finished and finished products.
② Research on steel heat treatment processes: The heat treatment principle of steel is based on the phase transformation of steel during heating and cooling, and metallographic technology is an important experimental method for such research.
③ Development of shape memory alloys: Shape memory alloys were discovered through metallographic analysis.
④ Failure analysis: Deformation, fracture, wear, corrosion and other forms of failure are hardly avoidable for mechanical equipment and parts in service. Metallographic inspection is adopted to find out the causes and take preventive measures.
⑤ Accident analysis: It is applied to the analysis and evidence collection of fire accidents in the field of fire cause identification, featuring repeatability, comparability and good visibility.
