Theoretical estimates of changes in the strength of SHS 
products that take place during their sintering and cooling are proposed. 
The possibility of passing from the mechanism of diffusion sintering 
to the mechanism of sintering by compaction of the material under 
the action of external mechanical loads has been taken into account. 
It has been shown that the competition between these mechanisms of 
sintering under cooling of products is responsible for the nonmonotonic 
character of the dependence of the strength of product on the delay 
time.
