The main methods to improve the tensile strength of cemented carbide are as follows:
1. Adjust alloying elements: By adjusting the content of alloying elements, such as increasing the content of chromium, the thermal strength and corrosion resistance can be improved. Increasing the content of nickel and molybdenum can improve corrosion resistance and strength, while the addition of cobalt can increase the hardness of steel. and wear resistance.
2. Use appropriate heat treatment processes: According to different alloy materials, design appropriate heat treatment processes and optimize their organizational structures to improve tensile strength.
3. Choose the appropriate processing method: According to the properties and requirements of the material, choose the appropriate processing method. For example, extrusion can improve the strength of aluminum alloy, and cold drawing can improve the strength of stainless steel.
In general, these methods can improve the tensile strength of cemented carbide to a certain extent, but they need to be combined with the actual situation to achieve overall performance improvement.
