Název v původním jazyce

Crystallization mechanisms occurring in the Se-Te glassy system

Popis výsledku v původním jazyce

Crystallization kinetics, studied under non-isothermal conditions in dependence on particle size, is reviewed for the Se-Te glassy system, with particular focus on occurring macroscopic crystallization mechanisms. The observed complexity of the crystallization processes is explained in terms of the two previously identified mechanisms-bulk crystallization originating from nuclei randomly distributed in the volume of each glass particle (formation of these nuclei is consistent with the classical nucleation theory) and crystallization from surface/volume active centers, dislocations, structural defects, and heterogeneities originating from the mechanical damage of the material (e.g., during grinding and milling). In addition, a new crystallization mechanism, previously unobserved in this system, was revealed for hyperquenched Se95Te5 glass. The origin of this mechanism is suggested to be closely associated with the stress-induced defects contained in the highly strained structure of this
