Sinter zone: Under the action of a large amount of heat released by the combustion of the fuel in the sinter, the gangue and part of the iron minerals in the mixture melt and form slagging, thus melting occursResearch on vacuum annealing of titanium alloys In the liquid phase, as the combustion layer moves downward and the cold air passes, the temperature of the material gradually decreases, and the molten liquid phase is cooled and solidified into sinter with a porous structure. High temperature melt is solidifyingBrazing requirements for carbide woodworking tools During the solidification process, new minerals are crystallized and precipitated. The air permeability of the sinter layer is better than that of the mixed material. Therefore, the gradual thickening of the sinter layer makes the air permeability of the entire material layer better, and the vacuumDebinding and sintering of metal injection molding components The main change in this layer as the temperature becomes lower is: the high-temperature melt solidifies into sinter, accompanied by crystallization and precipitation of new minerals. At the same time, the cold air drawn in is heated, and the sinter is Cooling, low-valent oxides in contact with air may be oxidized again.Effect of filler metal on vacuum brazing of cemented carbide and steel
