THEORETICAL STUDY OF PRODUCTION OF UNIQUE GLASSES IN SPACE

摘要

The overall objective of this program is to develop analyti¬cal functional relationships describing homogeneous nucleation and crystallization in various supercooled liquids. The time and temperature dependent relationships of nucleation and crystallization (intrinsic properties) are being used to relate glass forming tendency to extrinsic parameters such as cooling rate through computer simulation.nThe literature has been reviewed and critically analyzed, and kinetic equations have been developed for homogeneous and heterogeneous nucleation and subsequent crystal growth. The kinetic relationships have been applied to known glass formers and non-glass formers.
