Lijia introduces the four basic stages of the tungsten steel sintering process
The removal of the forming agent and the pre-sintering stage. At this stage, the sintered body undergoes the following changes
Removal of molding agent in the early stage of sintering. As the temperature increases, the molding agent gradually decomposes or vaporizes and is expelled from the sintered body. At the same time, the molding agent adds more or less carbon to the sintered body. The amount of carbonization will depend on the type and quantity of the molding agent and the sintering process. Changes due to different processes.
The oxides on the powder surface are reduced. Hydrogen can reduce the oxides of cobalt and tungsten at the sintering temperature. If the carbon-oxygen reaction is not strong during vacuum removal of the molding agent and sintering. The contact stress between the powder particles is gradually eliminated, and the bonded metal powder begins to recover and recrystallization surface diffusion begins to occur. The strength of the compact is improved.
Solid phase sintering stage (°C eutectic temperature)
At the temperature before the emergence of the liquid phase, in addition to continuing the process that occurred in the previous stage, the solid phase reaction and diffusion are intensified, plastic flow is enhanced, and the sintered body appears obviously of contraction.
Liquid phase sintering stage (eutectic temperature sintering temperature)
When the sintered body appears in the liquid phase, the shrinkage is quickly completed, followed by crystallization transformation to form the basic structure and structure of the alloy.
Cooling stage (sintering temperature room temperature)
At this stage, the structure and phase composition of tungsten steel will undergo certain changes with different cooling conditions. This feature can be used to heat treat tungsten steel to improve its physical properties. Mechanical behavior.
