“…Importantly, the critical void size for the onset of void ordering is much smaller than the void saturation radius predicted by the theory for voids distributed randomly. Hence, the saturation of swelling observed in void lattices cannot be a consequence of this, as was thought before [8,9]. This statement is also supported by a previous finding that the formation of the free channels between voids in void lattices provides the escape routes for the SIA clusters to dislocations and leads to a significant increase of the void saturation radius [39].…”

“…Voids in hcp Mg (and bubbles in hcp Ti, Co, Zr and some Zr alloys) can order in planes parallel to the basal plane with variable void plane separation [6,7]. Jäger and Trinkaus concluded that for hcp metals a decision between 1-D or 2-D SIA transport proposed by Evans [8][9][10] was not possible at the moment due to the lack of a sufficient body of information. Now we know from molecular dynamics (MD) simulations using empirical potentials for the inter-atomic interaction that SIA clusters bigger than four SIAs in hcp Zr migrate one-dimensionally in the basal plane [11].…”

On the onset of void ordering in metals under neutron or heavy-ion irradiationAlexander V Barashev, Stanislav I Golubov To cite this version:Alexander V Barashev, Stanislav I Golubov. On the onset of void ordering in metals under neutron or heavy-ion irradiation. Philosophical Magazine, TaylorFrancis, 2010, 90 (13) Formation of void lattices is observed in a number of metals and alloys under high-energy particle bombardment. Here we derive the conditions for destabilisation of homogeneous void arrangement using an approach developed for the description of lane formation in pedestrian crowds. The model is based on the Foreman's mechanism of void alignment due to onedimensionally-migrating clusters of self-interstitial atoms. The results show that spatial correlations between voids should exist above some very small size, unless correlations with other defects prevail. It is shown that spatial correlations of voids with dislocations and secondphase precipitates should also evolve and provide a powerful driving force for further swelling.

“…The swelling for the ODS molybdenum material was estimated to be less than ~1 % for the low fluence material and less than ~2.4 % for the material irradiated to a fluence of ~6 x 10 21 n cm -2 . Literature data have indicated that the irradiation swelling of molybdenum is very low (Brimhall et al 1973, Gelles et al 1981, Abe et al 1993, Evans 1980. Volumetric swelling of 0.12 % has been reported for unalloyed molybdenum irradiated to 970 °C to a fluence of 1.96 x 10 21 n cm -2 (Brimhall et al, 1973).…”

“…Кристаллическая струк-тура α-фазы очень сложна и содержит 176 атомов. При температуре, соответствующей первому фазовому переходу, происходит искажение элементарной ячей-ки [6]. Структура β-фазы была определена с помощью нейтронной и синхротронной рентгеновской дифракций и является кубической с пространственной группой F43c(T s d ) [7].…”

Исследовано влияние замещения ионов марганца на структурные, диэлектрические, транспортные и магнитные свойства Bi2(Sn0.9Mn0.1)2O7, определена их взаимосвязь. Методом дифференциальной сканирующей калориметрии обнаружены смена типа тепловых эффектов и знака термоэдс при полиморфных переходах. Определена парамагнитная температура Кюри, антиферромагнитное взаимодействие в мартенситной и аустенитной фазах. Установлен тип носителя тока. Работа выполнена при финансовой поддержке Российского фонда фундаментальных исследований, Правительства Красноярского края, Красноярского краевого фонда поддержки научной и научно-технической деятельности в рамках научных проектов N 16-52-00045 Бел\_а.
