FAST (Field-assisted Sintering Technology)/ DCS (Direct Current Sintering) is an advanced powder metallurgy technology that integrates plasma activation, pressurization, heating and sintering of alloy powders. Under the combined action of current and pressure, materials can be synthesized in only one step. With its rapid heating and cooling rates, high sintering efficiency and good connection effect, it has attracted widespread attention and heated discussions among researchers. With the continuous deepening of research, this technology has been widely used in the preparation of various materials, such as metals, ceramics, and composite materials. Including materials that are not easy to sinter, novel carbon-containing materials, most nanocrystalline metal functional gradient materials and materials with complex shapes.

Particle size, particle shape, powder caking and agglomeration, particle size distribution, admixtures, etc. will influence sintering.
Hot pressing sintering is a method of sintering a blank by applying pressure at high temperatures. We widely use this method in powder metallurgy and high-temperature material industries.
The hot isostatic pressing process is to subject the powder to high temperature and isostatic pressure to sinter it into a dense part.
Microwave sintering is a method of generating heat by coupling the special waveband of microwaves with the basic microstructure of materials.
One type of sintering process in which the powder is not completely densified in the solid phase is called solid state sintering.
Liquid phase sintering is the process of introducing certain additives during the sintering process to form the glass phase and liquid phases.
FAST sintering cemented carbide has advantages compared with vacuum sintering, such as inhibiting grain growth, obtaining fully dense, etc.
In recent years, SPS technology has been successfully applied to the connection of different materials and has shown satisfactory results.
