Understanding Homogeneous Nucleation in Solidification of Aluminum by Molecular Dynamics Simulations (OPEN ACCESS)

Homogeneous nucleation from aluminum (Al) melt was investigated by million-atom molecular dynamics (MD) simulations utilizing the second nearest neighbor modified embedded atom method (MEAM) potentials. The natural spontaneous homogenous nucleation from the Al melt was produced without any influence of pressure, free surface effects and impurities. Initially isothermal crystal nucleation from undercooled melt was studied at different constant temperatures, and later superheated Al melt was quenched with different cooling rates.

A new model to predict grain nucleation during dynamic recrystallization

Deformation in metals and alloys is accompanied by high hardening rates and high dislocation 

content. Static annealing of deformed metals or forming operations at elevated temperatures can 

lead to static and dynamic recrystallization (SRX and DRX). The resultant texture and hence the 

properties of such a material are determined by the nucleation and growth of recrystallized grains

Post Doctoral Appointment in Thin Film and Grain Growth Modeling

Professor Gregory B. Thompson at the University of Alabama seeks post doctoral applicants for thin film and grain growth modeling in metal alloys. The qualified candidate will use modeling to explain and help direct experimental studies.

Spatial Control in the Heterogeneous Nucleation of Water

The attache d paper was recently published
in Applied Physics Letters. We show for the first time that Nucleation and
Condensation of Water can be spatially controlled. Such control of nucleation
phenomena and the fundamental findings discussed in the paper have implications
for the Energy and Water industry. The paper can be found at http://link.aip.org/link/?APL/95/094101/1
