Abstract
A detailed numerical and experimental study of the ordering of the low -temperature tetragonal phase of CuAu is presented. The numerical simu lations are based on a coarse-grained free energy derived from electro nic structure calculations of CuAu, while the experimental results are obtained from in situ. X-ray scattering. Both theoretical and experim ental work indicate a subtle kinetic competition between the ordered t etragonal phase and the metastable modulated phase.
