“…Later studies performed for bcc metals (iron, niobium, molibdenum) which exhibit stacking faults energy more than 140 mJ/mol showed that there are two types of structure are formed in result of HPT treatment. The structure of the first type consists of dislocation cells, and the second type is formed by microcrystallites [14,16,[18][19][20][21]. It is well known, that the formation of dislocation cells is due to the motion and interaction of individual dislocations, while microcrystallites are formed due to rotational deformation modes with the participation of collective disclination effects.…”

“…1) не сопровождается сколько-нибудь заметным деформационным упрочнением и до n = 2 сравнима с установившейся стадией (кривая 3 на рис. 1) для КВД кристаллической меди, где, как известно [13][14][15], не наблюдается деформационно-индуцированных фазовых превращений. Сравнение кривых s(n) и V (n) приводит к выводу о том, что уже при деформации (n ≥ 2) исходно кристаллический сплав почти полностью переходит в аморфное состояние (V ≈ 0.1).…”
