The study of primary recrystallization processes in deformable aluminu
m alloys that have not been hardened by heat treatment makes possible
a substantiated choice of technological conditions for pressure shapin
g. The data from metallographic analysis of the primary recrystallizat
ion of alloy 1570 are inadequate in comparison with the data for its i
ndustrial analog, alloy AMg6. In view of this we studied the distincti
ve features of primary recrystallization in semi-finished alloy 1570 s
trip.
