Influence of Sintering Temperature on Cemented Carbide Strips Revealed

Carbide strip is an important engineering material and is widely used in various industrial fields. Sintering is a key step in the preparation process of cemented carbide, and its sintering temperature has a decisive impact on the performance of the product. Sintering temperature refers to the temperature reached by cemented carbide strips during the sintering process. It directly affects parameters such as the bonding strength between metal particles, the growth rate of grains, and the distribution of residual stress.

First, the sintering temperature has an important influence on the density and crystallinity of the cemented carbide strip. At high temperatures, the bond between metal particles will be stronger and the long strip texture will be more uniform and dense, thereby improving the strength and hardness of cemented carbide. At the same time, the growth rate of grains will also increase at high temperatures, which is conducive to recrystallization of grain boundaries, thus improving the crystallinity and creep resistance of the alloy.

Secondly, the sintering temperature will also affect the residual stress distribution of the cemented carbide strip. At high temperatures, cemented carbide will undergo greater shrinkage and deformation during the cooling process, resulting in greater residual stress inside the strip. If the sintering temperature is too high, residual stress may cause cracks or deformation of the strips, affecting the processing performance and service life of the product.

In addition, sintering temperature also affects the grain size and distribution of cemented carbide strips. At high temperatures, the diffusion rate between metal particles increases, the grains grow more rapidly, the grain size becomes larger, and the grain distribution becomes more uniform. This has a positive impact on the mechanical properties and wear resistance of the cemented carbide.

In general, the sintering temperature has an important impact on the performance of cemented carbide strips. By reasonably controlling the sintering temperature, the microstructure and mechanical properties of the alloy can be adjusted and the overall performance of the product can be improved. Therefore, in production practice, optimized product performance should be achieved by strictly controlling sintering parameters according to specific alloy composition and process requirements.
