Development of an Interatomic Potential for the Simulation of Defects, Plasticity and Phase Transformations in Titanium
M. I. Mendelev, T. L. Underwood, G. J. Ackland
New interatomic potentials describing defects, plasticity and high temperature phase transitions for Ti are presented. Fitting the martensitic hcp-bcc phase transformation temperat…
Efficacious calculation of Raman spectra in high pressure hydrogen
G. J. Ackland, I. B. Magdau
We present and evaluate an efficient method for simulating Raman spectra from molecular dynamics (MD) calculations {\it without} defining normal modes. We apply the method to high…
Probing atomic environments in alloys by electron spectroscopy
T. L. Underwood, G. J. Ackland, R. J. Cole
In alloys exhibiting substitutional disorder, the variety of atomic environments manifests itself as a `disorder broadening' in their core level binding energy spectra. Disorder br…
Molecular Dynamics and OKMC Study of Radiation Induced Motion of Voids and He Bubbles in BCC Iron
G. J. Galloway, G. J. Ackland
We show that voids adjacent to radiation damage cascades can be moved in their entirety by several lattice spacings. This is done using molecular dynamics cascade simulations in ir…
