Crystallization kinetics of glasses
Thermophysical bases of vitrification and crystallization are discussed in terms of the enthalpy versus temperature diagram and its derivative (DTA) illustrating relaxation and glass transformation as well as crystallization of glassy and amorphous states to form stable and metastable phases. Non-isothermal kinetics are thoroughly discussed and the use of one(JMAEK) and two(SB) parameter equati...
متن کاملCrystallization Kinetics of Metallic Glasses
Metallic glasses are kinetically metastable materials. Metallic glass is defined as “A liquid, which has been cooled into a state of rigidity without crystallizing”. Properties of metallic glasses differ form non metallic glasses. Ordinary glasses are made up of silica while metallic glasses are made of alloy metals. Ordinary glasses are transparent whereas metallic glasses are opaque. In ordin...
متن کاملCrystallization Kinetics of Chalcogenide Glasses
Chalcogenide glasses are disordered non crystalline materials which have pronounced tendency their atoms to link together to form link chain. Chalcogenide glasses can be obtained by mixing the chalcogen elements, viz, S, Se and Te with elements of the periodic table such as Ga, In, Si, Ge, Sn, As, Sb and Bi, Ag, Cd, Zn etc. In these glasses, short-range inter-atomic forces are predominantly cov...
متن کاملCrystallization of Liquids and Glasses
The scientific and technological importance of advanced materials are summarized. The goverriing theories of glass transition, crystal nucleation and crystal growth are combined with t he overall theory of transformation kinetics to clarify the phenomenon of glass formation from the liquid state. Finally, examples of novel glasses as well as gIassceramics obtained from the controlled crystalliz...
متن کاملCrystallization of hard-sphere glasses.
We study by molecular dynamics the interplay between arrest and crystallization in hard spheres. For state points in the plane of volume fraction (0.54 <or= varphi <or= 0.63) and polydispersity (0 <or= s <or= 0.085), we delineate states that spontaneously crystallize from those that do not. For noncrystallizing (or precrystallization) samples we find isodiffusivity lines consistent with an idea...
