Journal ArticleDOI
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
Icosahedral Order, Frustration, and the Glass Transition: Evidence from Time-Dependent Nucleation and Supercooled Liquid Structure Studies
TL;DR: The first quantitative measurements of the time-dependent nucleation rate in a Zr59Ti3Cu20Ni8Al10 bulk metallic glass are combined to provide strong support for an icosahedral-order-based frustration model for the glass transition in Zr-based glasses.
Journal ArticleDOI
The effect of phase separation on subsequent crystallization in Al88Gd6La2Ni4
TL;DR: In this article, the authors studied the devitrification kinetics of Al-rich Al-RE-TM (RE=rare earth, TM=transition metal) amorphous alloys.
Journal ArticleDOI
Mechanisms for nanocrystal formation in metallic glasses
Kenneth F. Kelton,T. K. Croat,Anup K. Gangopadhyay,L. Q. Xing,A.L. Greer,Matthew Weyland,X. Li,Krishna Rajan +7 more
TL;DR: In this article, transmission electron microscopy (TEM) data prove that nanoscale phase separation occurs prior to crystallization in some Al-transition metal-rare earth glasses.
