Zeiss research grade Axio Scope.A1 optical microscope
Amplification of Microscope: 12.5X——1000X
Main function of metallographic microscope:
1. The structure of iron and steel materials (conventional structure, precipitated phase, Detrimental phase) analysis, morphology photography.
2. Type analysis and grade evaluation of inclusions of iron and steel materials.
3. Evaluation of grain size of iron and steel materials.
4. Widmannstatten structure analysis and grade evaluation of iron and steel materials.
5. Banded structure analysis and grade evaluation of iron and steel materials.
6. Decarburization layer analysis on surface of iron and steel materials.
7. Evaluation of spheroidization grade of iron and steel materials.
8. Depth measurement and morphology analysis of surface clad layer, infiltration layer and hardening layer of iron and steel materials.
9. Defects analysis of iron and steel materials (continuous casting billet, rolled material, forging material, etc.).
10. Failure analysis of finished products and parts of iron and steel materials.
