Metal composition analysis and testing projects mainly include the following aspects, aiming to determine the chemical, physical and mechanical properties of metal materials and ensure that their quality and performance meet the requirements for use. The following are specific test items:
1. Chemical composition analysis:
This is the main part of metal composition analysis, which involves the analysis of various elements in metal materials, such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), nickel (Ni) ), chromium (Cr), molybdenum (Mo), copper (Cu), vanadium (V), titanium (Ti), tungsten (W), lead (Pb), niobium (Nb), mercury (Hg), tin (Sn) ), cadmium (Cd), antimony (Sb), aluminum (Al), magnesium (Mg), iron (Fe), zinc (Zn), nitrogen (N), hydrogen (H), oxygen (O), etc.
Through chemical composition analysis, the main components and impurity content of metal materials can be understood, providing basic data for material performance evaluation and use.
2. Metallographic test:
Metallographic testing mainly focuses on the microstructure and surface morphology of metal materials, including non-metallic inclusions, low-magnification structures, grain size, fracture inspection, etc.
These tests help evaluate a material's processability, service life, and potential performance issues.
3. Mechanical performance testing:
Mechanical property testing involves testing various mechanical properties of metal materials, such as tensile test, compression test, shear test, torsion test, bending test, impact test, etc.
In addition, it also includes hardness tests such as Rockwell hardness test, Brinell hardness test, and Vickers hardness test.
These tests can evaluate the strength, toughness, hardness and other mechanical properties of materials, providing a basis for material selection and use.
4. Non-destructive testing and material certification:
Non-destructive testing is a non-destructive testing method that uses advanced means such as X-ray fluorescence spectrometry, mass spectrometry, and ion chromatography to detect internal defects in metal materials.
Material certification is to verify the material of metal materials through testing methods to ensure that they meet the corresponding standards and requirements.
