First X-Ray Scattering Studies on Electrostatically Levitated Metallic Liquids: Demonstrated Influence of Local Icosahedral Order on the Nucleation Barrier
Kenneth F. Kelton,Geun Woo Lee,Anup K. Gangopadhyay,Robert W. Hyers,T. J. Rathz,Jan R. Rogers,Michael B. Robinson,D. S. Robinson +7 more
TL;DR: The first direct experimental demonstration of Frank's complete hypothesis is presented, showing a correlation between the nucleation barrier and a growing icosahedral short-range order with decreasing temperature in a Ti39.5Zr 39.5Ni21 liquid.
Journal ArticleDOI
Difference in icosahedral short-range order in early and late transition metal liquids.
Geun Woo Lee,Anup K. Gangopadhyay,Kenneth F. Kelton,Robert W. Hyers,T. J. Rathz,Jan R. Rogers,D. S. Robinson +6 more
TL;DR: This is the first experimental observation of distorted icosahedral short-range order in any liquid, although this has been predicted by theoretical studies on atomic clusters.
Journal ArticleDOI
Beamline electrostatic levitator for in situ high energy x-ray diffraction studies of levitated solids and liquids
Anup K. Gangopadhyay,Geun Woo Lee,K. F. Kelton,Jan R. Rogers,Alan I. Goldman,D. S. Robinson,T. J. Rathz,Robert W. Hyers +7 more
TL;DR: In this paper, an adaptation of electrostatic (ESL) for in situ structural studies of a wide range of materials using high energy (30-130keV) x rays at a synchrotron source is described.
Journal ArticleDOI
Link between liquid structure and the nucleation barrier for icosahedral quasicrystal, polytetrahedral, and simple crystalline phases in Ti-Zr-Ni alloys: Verification of Frank's hypothesis
