What is a metal fracture?
When a metal is broken by an external force, two matching sections are left at the fracture site, which is called a "fracture". The shape and appearance of this fracture contains a lot of important information about the fracture process.
By observing and studying the morphology of the fracture, we can analyze the cause, nature, mode, mechanism, etc., and also understand the details of the stress condition and crack expansion rate at the time of fracture. Like a "scene", the fracture retains the whole process of fracture occurrence. Therefore, for the study of metal fracture problems, observation and analysis of fracture is a very important step and means. Scanning electron microscope has the advantages of large depth of field and high resolution, and has been widely used in the field of fracture analysis.
Application of Scanning Electron Microscope in Metal Fracture Analysis
There are various forms of failure of metal fracture. Categorized by the degree of deformation before fracture, they can be divided into brittle fracture, ductile fracture, and mixed brittle and ductile fracture. Different fracture forms will have characteristic microscopic morphology, which can be characterized by SEM to help researchers to quickly perform fracture analysis.
