TLDR
In this article, a new set of experimental data concerning primary nucleation, kinetics and modes of crystallization of supercooled liquid selenium is presented, covering the whole supercooling range from the glass transition (30°C to the crystal melting point (221°C).About:

Journal ArticleDOI
A general mechanism of polycrystalline growth.
TL;DR: Phase-field simulations show that the presence of particulates or a small rotational–translational mobility ratio in crystallizing fluids give rise to similar growth patterns, implying a duality in the growth process in these structurally heterogeneous fluids.
Journal ArticleDOI
Growth Actuated Bending and Twisting of Single Crystals
TL;DR: How and why so many materials choose dramatic non-crystallographic distortions is analyzed, with an emphasis on crystal chemistries that give rise to stresses operating either on surfaces of crystallites or within the bulk.

Fast and slow crystal growth kinetics in glass-forming melts
Jiri Orava,A.L. Greer +1 more
TL;DR: Despite the difference of more than 11 orders of magnitude in U(max) seen in pure metals and in silica, the range of glass-forming systems surveyed fit into a common pattern in which the lability increases with lower reduced glass-transition temperature (T(g)/T(m)) and higher fragility of the liquid.

Growth of polyethylene single crystals from the melt: Morphology
Akihiko Toda,A. Keller +1 more
TL;DR: In this article, the origin of the chair-like crystals has been discussed and a possible mechanism has been suggested for the formation of spiral terraces; the mechanism is based on a distortion caused by the three-dimensional shape of chairlike crystals.
Journal ArticleDOI
Morphology development and exclusion of noncrystalline polymer during crystallization in PVDF/PMMA blends
TL;DR: In this paper, a coarse spherulite obtained at a high T C of 162°C was found to be developed with a two-step crystallization process, and the ordering in the spheruleites (P r) increased with time at the early stages and then decreased at the later stages.

The Growth of Crystals and the Equilibrium Structure of their Surfaces
TL;DR: In this paper, it was shown that the rate of growth of a surface containing dislocations is proportional to the square of the supersaturation for low values and to the first power for high values of the latter.
Journal ArticleDOI
On the relations between structure and morphology of crystals. I
P. Hartman,W. G. Perdok +1 more
TL;DR: In this paper, Hartman and Perdok made an attempt to find relations between crystal structure and crystal morphology on an energy basis, and concluded that the morphology of a crystal is governed by chains of strong bonds running through the structure.

A Phenomenological Theory of Spherulitic Crystallization
H. D. Keith,F. J. Padden +1 more
TL;DR: In this article, the origins of fibrous crystal habits in the absence of appreciable temperature gradients and profuse non-crystallographic branching are explained, and it is shown that a plane crystal face cannot grow without suffering an instability of profile.

The spherulitic and lamellar morphology of melt-crystallized isotactic polypropylene
D.R. Norton,A. Keller +1 more
TL;DR: In this paper, the basic morphology of melt-crystallized isotactic polypropylene (iPP) was investigated using both optical and electron microscopy, and specific correlations were obtained between the structural entities on all scales of the structure hierarchy.
