“…Besides, Saito et al [1] reported that the Zr-O atom clusters, which distributed densely over an extremely short range, could effectively inhibit the dislocation activity. Since the proliferation of dislocations can be suppressed and small number of dislocations are involved in the plastic deformation, the stress exponent is low compared with other RT creep of alloys [26,27].…”

“…The creep behaviour of UFG materials may be influenced by synergetic effect of additional creep mechanisms like GBS, cavitation or more intensive diffusion processes. The influence of synergetic effect of additional creep mechanisms on creep behaviour of UFG materials may be supported by the value of stress exponent n often involving intragranular dislocation process and concurrently an observation of GBS or cavitation [15,16].…”

“…В связи с этим разработка путей получения титана с высокими механическими ха-рактеристиками и исследование структурных особенно-стей, их определяющих, являются одной из важных задач современного материаловедения. В настоящее время для решения этой задачи широко используется перевод тита-на [1][2][3][4], как и других металлов и сплавов [5][6][7], в нано-и микрокристаллическое состояние за счет воздействия различных режимов интенсивной пластической дефор-мации (ИПД). Основными структурными факторами, определяющими высокие механические характеристики после ИПД, являются размер зерен, состояние и струк-тура границ зерен, включая их разориентацию.…”
