The effect of the properties of metal raw materials on metal tensile properties

Metallic materials are the general term for materials with metallic characteristics, usually composed of metallic elements or metallic elements, mainly including pure metals, special metals, alloys, and intermetallic compounds of metallic materials.

During the processing of metal materials, its structure is affected to a certain extent and changes accordingly. The special properties of metal materials are mainly manifested in the following aspects:

• 1. Many metal materials need to be subjected to AC loads during work. Under this action, the yield limit of metal materials is much higher than the stress level, but after long-term stress cycles, brittle fracture will suddenly appear. This phenomenon is the most common and dangerous rupture form of fatigue in metallic materials.
• 2. Under the action of load external force, the ability of metal material to not be damaged by permanent deformation is the plasticity of metal material. The better the plasticity of the metal material, the plastic deformation will be formed in a larger range, the strength of the metal material will be strengthened during the plastic deformation process, and the safety of the metal material will be improved.
• 3. Hardness mainly refers to the resistance of metal materials that press hard objects on the surface, and is one of the important indicators for considering the properties of metal materials. The hardness of the metal material is the result of the initial plastic deformation resistance and the continuous plastic deformation resistance. Generally speaking, the higher the hardness of the metal material, the better the wear resistance.
