摘要：
A two-velocity quasistationary model for the combustion of low-gas compositions in a press mold subjected to a constant load is used to analyze the feasibility of obtaining high-density materials through various unilateral extrusion schemes. Structural transitions in systems with a low-melting component are examined in the region of the liquid phase. It is shown that obtaining compacted products depends on the amount of the liquid phase and the relationship between the densities of the initial and final materials. Formulas are obtained for estimating the required loads for production of low-porosity products. The effect of a low-melting additive on the formation of composites durign forced compacting in self-propagating high-temperature synthesis (SHS) is analyzed.
