Properties of Bulk Metallic Glasses

Abstract: Металловедение и термическая обработка Izvestiya vuzov. Tsvetnaya metallurgiya • 6 • 2016 71 ВведениеМеталлические стекла, получаемые в виде тон-ких чешуек или лент, известны со второй полови-ны прошлого века [1]. Объемные металлические стекла (ОМС) с минимальным размером порядка 100-102 мм в каждом из 3 пространственных из-мерений [2] изначально были получены в системах Pd-Cu-Si и Pd-Ni-P, но ввиду исключительной дороговизны основного компонента (палладия) долгое время не представляли особого интере-са для… Show more

“…In plastic deformation it is assumed that (E a −σ a 3 0 ) ≤ 0, while in inelastic deformation (E a −σ a 3 0 ) > 0, therefore inelastic deformation is thermoactivated. However, the inelastic deformation effect is observed experimentally at cryogenic temperature (77 K) [22], where the thermal fluctuation energy is low (0.007 eV), and at lower temperatures [23]. Therefore, it is important to establish the physical mechanism of inelastic deformation of metallic glasses within the room temperatures range and below.…”

“…(24) Thus, with a fixed parameter 0 ≤ η < 1, function F(η, ϕ) can describe the non-equilibrium transition of the first kind from amorphous (ϕ 1 = 0) to nanocrystalline state (ϕ 3 = 1) through the potential barrier F η, ϕ 2 (η) . Analyzing (22), we can see that function F(η, ϕ) in the definition domain of variables 0 ≤ η < 1, 0 ≤ ϕ ≤ 1 has two minima (η, 0), (η, 1); one maximum 0, 1 2 and three saddle points (0,0), (0,1), η, 1 2 [1−η] . With η = 1 the potential barrier F η, ϕ 2 (η) disappears, point (1,0) becomes an unstable saddle-point, only one minimum (1,1) remains.…”
