The creep resistance of cemented carbide is excellent. Creep refers to the slow and continuous deformation of solid materials that occur under high temperature and stress for a long time. In high-temperature environments, most metals undergo a creep process, resulting in the loss of their structure and properties. However, carbide has excellent creep resistance, allowing it to be used at high temperatures for extended periods of time without losing its hardness, thus ensuring long-term accuracy and work efficiency.
The creep resistance of cemented carbide is mainly attributed to its unique structure and high hardness carbide particles. At high temperatures, the carbide particles in cemented carbide can hinder dislocation movement and grain boundary slip, thereby inhibiting the creep process. In addition, the high hardness of cemented carbide also gives it higher creep resistance. Compared with other metals, the creep rate of cemented carbide at high temperatures can be reduced by several orders of magnitude, thereby maintaining good structural and performance stability in high temperature environments.
To sum up, cemented carbide has excellent creep resistance, allowing it to be used in high temperature environments for a long time without losing its hardness and precision. This property makes it an ideal material for manufacturing tools and structural parts under high-temperature operating conditions.
