ABSTRACT:
The invention relates to the field of powder metallurgy, in particular to the design of autoclaves for manufacturing of composite materials by treatment of workpieces of discrete materials, mostly powders, at high pressures and temperatures.The autoclave module contains the vessel that includes hermetically sealed movable end closures, the rams restricting the axial shift of these closures, and the pressure yoke with columns and winding made of high-strength steel wire, whereby the pressure yoke is made in the form of three oval yoke sections—two lateral sections encompassing the rams, and one central section encompassing the rams and the vessel with closures, all of them equidistant from each other on the ram's length, whereby each of the lateral oval sections is made in such a way as to allow opposite shift while the central section is made in such a way as to allow shift in the direction which is perpendicular to the vessel's axis and parallel to the rams' axis, for a length ensuring free withdrawal of the rams and the end closures.The invention allows to reduce the metal consumption of the pressure module by a factor of 2 to 3 compared to the known analogs, and to enhance the reliability and the operational safety of the apparatus.
