The Sintering Process Of Tungsten Steel Can Be Divided Into Four Basic Stages:

1: Removal of forming agent and pre-burning stage. In this stage, the sintered body undergoes the following changes:

Removal of forming agent. As the temperature rises in the early stage of sintering, the forming agent gradually decomposes or vaporizes and is removed from the sintered body. At the same time, the forming agent more or less adds carbon to the sintered body. The amount of carbon addition will vary with the type and quantity of the forming agent and the sintering process.

The oxides on the powder surface are reduced. At the sintering temperature, hydrogen can reduce the oxides of cobalt and tungsten. If the forming agent is removed in vacuum and sintered, the carbon-oxygen reaction is not strong. The contact stress between the powder particles is gradually eliminated, the bonding metal powder begins to recover and recrystallize, surface diffusion begins to occur, and the strength of the compact is improved.

2: Solid phase sintering stage (800℃--eutectic temperature)

At the temperature before the liquid phase appears, in addition to continuing the process that occurred in the previous stage, the solid phase reaction and diffusion intensify, the plastic flow is enhanced, and the sintered body shrinks significantly.

3: Liquid phase sintering stage (eutectic temperature--sintering temperature)

When the liquid phase appears in the sintered body, the shrinkage is completed quickly, followed by a crystallization transformation, forming the basic organization and structure of the alloy.

4: Cooling stage (sintering temperature--room temperature)

In this stage, the organization and phase composition of tungsten steel undergo certain changes depending on the cooling conditions. This feature can be used to heat treat tungsten steel to improve its physical and mechanical properties.
