What are the factors that cause deformation of cemented carbide?

       What causes the deformation or bending of cemented carbide products after pressing and sintering?



After analysis, there are many reasons that affect the deformation and bending of the product. The reason for the deformation and bending of a certain product should be analyzed in a specific situation. Sometimes one factor plays a role, sometimes multiple factors play a role, and cannot be generalized.

Then, the causes of deformation and bending of cemented carbide products can be analyzed from the following aspects, and detailed work should be done in the production process.



1. Carbon gradient;



2. Cobalt gradient;



3. Temperature gradient;



4. The density gradient of pressed products;



5. Improper loading of the boat;

6. Shrinkage coefficient.
