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.
