What Is Relationship Between Fatigue Resistance Properties of Cemented Carbide And Fatigue Phenomena?

The fatigue resistance of cemented carbide is closely related to fatigue phenomena.

Fatigue phenomenon refers to the process in which materials undergo microstructural changes and macroscopic crack expansion after a certain number of stress cycles under the action of cyclic stress. This process can lead to fatigue fracture of the material, thus affecting the safety and operating efficiency of the equipment.

As an excellent wear-resistant material, cemented carbide’s fatigue resistance has a great impact on the durability of the material and the reliability of the equipment. Carbide with good fatigue resistance can effectively resist the expansion of fatigue cracks during long-term use, thereby avoiding or reducing the occurrence of fatigue fractures.

In addition, the fatigue resistance of cemented carbide is also related to the process conditions such as heat treatment and surface treatment during its manufacturing process. By optimizing process conditions, the fatigue resistance of cemented carbide can be improved, thereby extending its service life and the safe operation time of the equipment.

In summary, the fatigue resistance performance of cemented carbide is closely related to fatigue phenomena. By improving the fatigue resistance performance of cemented carbide, the expansion of fatigue cracks can be effectively delayed, and the durability of the material and the reliability of the equipment can be improved.
