“…Compared to face centered cubic (FCC) systems, where the correlation between incipient plasticity and dislocation motion has been well established [5,6,8,[14][15][16][17][18][20][21][22]. BCC systems are much more complex and, despite several reports [11][12][13][23][24][25][26][27][28][29], there are still many unanswered questions regarding our understanding of BCC-plasticity in nanocontacts encountered in indentation.…”

“…The importance of understanding near-surface mechanical behavior cannot be overstated given the rapidity with which device scaling has occurred (Cheng et al, 2006;Cordill, 2007;Cordill et al, 2009;Cross et al, 2006;Fischer-Cripps, 2004;Mook et al, 2008;Schuh et al, 2005;White et al, 2005). Additionally, the difficulty in atomistic simulations of such properties with realistic temperature and temporal variables has placed a burden of proof on experimental confirmation (Cordill et al, 2009;Cross et al, 2006;Schuh et al, 2005).…”

“…Additionally, the difficulty in atomistic simulations of such properties with realistic temperature and temporal variables has placed a burden of proof on experimental confirmation (Cordill et al, 2009;Cross et al, 2006;Schuh et al, 2005). Two of the techniques of choice have been atomic force microscopy (AFM) and nanoindentation which can drive sharp tips into the near-surface to extract modulus, hardness, flow stress, and creep data, among other mechanical properties.…”

“…Монокристаллический Аl (99.99%) взят как материал с хорошо изученной дефектной структурой, многократ-но исследованный методами традиционного NI [26][27][28]. Поверхность образцов Al размером 10 × 10 × 3 mm под-готавливалась механической шлифовкой с помощью аб-…”

“…При этом поведение дефектной структу-ры материалов в локальных сильнодеформированных объемах под инструментом/индентором в присутствии низкочастотных виброакустических колебаний изучено недостаточно. Правда, в последнее время появились экспериментальные свидетельства того, что физико-механические свойства ряда металлических материа-лов [4, 7,12,23,24,[26][27][28] при локальном нагружении мо-гут значительно измениться при наложении дополни-тельных гармонических осцилляций нагрузки.…”
