◆Morphology observation：

The scanning electron microscope can be used to observe the surface and fracture topography of metal materials with high resolution, such as cracks, pores, inclusions, etc. This observation is essential for understanding the microstructure and properties of the material.

◆Structure analysis：

Through the structure analysis of metal materials, the phase composition, grain morphology and grain boundary structure of the materials can be understood. This information is of great significance for optimizing the preparation process and improving the properties of the materials.

◆Energy dispersive spectrometer（EDS）：

When the scanning electron microscope is used in combination with the energy dispersive spectrometer (EDS), it is possible to perform quantitative analysis of the micro area composition while observing the topography. It helps to understand the distribution of the elements in the material and the influence of the elements on the properties of the material.

◆Fracture analysis：

Metal materials may fail by fracture during use. By observing the fracture morphology through the scanning electron microscope, the starting point, expanding path and type of the fracture (such as brittle fracture, ductile fracture, etc.) can be analyzed, so as to deduce the cause of the fracture.

◆Inclusion and defect analysis：

Inclusions and defects in metals are often significant contributors to failure. The scanning electron microscope can clearly show the morphology, size and distribution of inclusions and defects, providing an important basis for failure analysis.
