Hi Guys,
The last months we have been simulating a grain boundary in copper.
When metals are analyzed on the microspic scale they consist of regions where the atoms are arranged in a perfect lattice. The regions of perfect structure are know as grains. A chunk of metal consist of lots of grains and a better understanding of what goes on in the regions where the different grains meet, the grain boundary, would be valuable.
Our aim is to get a knowlegde about the structural changes when the grain boundary is just left alone. With this information it becomes possible to give a description of the most probal structure in the regions where the atoms are not aligned in a perfect lattice.
From an engeneering point of view the knowlegde could help explaining the strength of metals.
The data we obtained for the magnesium deposition have not yet been analyzed. The reason is that we are about to make a simulation that is very alike, and we have therefore decided to collect this data also before doing any data processing.
Take care
Andreas
