| Abstract: | Dependences are considered for the characteristic times of the main stages of the SHS compaction process—synthesis, compaction, and cooling — on the geometric size of a charge billet and the composition of a synthesized hard alloy. The existence is shown of two critical sizes for a starting billet which limit the region of producing a nonporous material. The presence of the critical conditions depending on the liquid phase fraction formed in the synthesis of a hard alloy is established. A satisfactory qualitative and quantitative agreement of calculated and experimental results is obtained.Institute of Structural Macrokinetics, Russian Academy of Sciences, Chernogolovka.
