Molecular liquids can develop a fast mode of crystal growth ("GC-growth") near the glass transition temperature. This phenomenon remains imperfectly understood with several explanations proposed. We report that GC growth in o-terphenylconserves the overall volume despite a 5% higher density of the crystal, and produces fine trys grains with the same unit cell as normally grown crystals. These results indicate that GC growth continuously creates and free surfaces, possibly by fracture. This aspect of the phenomenon ha S not been considered by previous, treatments and is a, difficulty for those niodels that hypothesize a 5% strain without Voids. Given the existence of.even faster crystal growth on the free surface of Molecular glasses, we consider the possibility that.GC growth is facilitated by fracture and surface mobility. This notion has support from the fact that GC growth and Surface growth are both highly correlated with surface diffusivity and with fast crystal growth along preformed tracks, in the glass.
