Evolyutsiya Defektnoy Struktury V Tverdykh Telakh

Vazhnuyu rol' v protsessakh, protekayushchikh pri poluchenii i obrabotke metallov, igrayut strukturnye defekty (vakansii, dislokatsii, granitsy zeren i t.d.). Dlya opisaniya stol' razlichnykh po masshtabu ob"ektov v rabote predlozheny modeli, baziruyushchikhsya na metodakh molekulyarnoy dinamiki i neravnovesnoy termodinamiki. Na ikh osnove issledovany takie yavleniya, kak spontannaya lokalizatsiya sluchaynykh voln v nelineynykh tsepochkakh, vzaimnye perekhody malopodvizhnykh i podvizhnykh dislokatsiy s uzkim i shirokim dislokatsionnym yadrom, teksturnoe formirovanie pri vytyagivanii struktur blizkikh k ideal'nym kristallicheskim usam i t.d. V ramkakh dvukhurovnevoy dvukhmodovoy modeli polucheny edinye krivye uprochneniya pri intensivnoy plasticheskoy deformatsii, kotorye vklyuchayut v sebya uchastki zakona Kholla-Petcha, lineynogo i kvadratichnogo zakona uprochneniya. A takzhe rassmotreny avtokolebatel'nye perekhody v amorfnykh splavakh, yavleniya stick-slip v smazkakh, yavleniya zonal'nogo razrusheniya vokrug tsilindricheskikh polostey i t.d. Kniga mozhet predstavit' interes dlya spetsialistov v oblasti neravnovesnoy termodinamiki, a takzhe v oblasti materialovedeniya, obrabotki metallov s primeneniem metodov intensivnoy plasticheskoy deformatsii.
