First paper

Recently I have spent a lot of time preparing my first paper related to PhD project. I hope it will be published in the 3D Materials Science conference proceedings. Its title is “A Toolbox for Geometric Grain Boundary Characterization” which means I have focused on short description of package of software tools developed by myself during last months. Writing this paper was a great opportunity to sum up my results and put them in the right order. We are now able to fully characterize a given boundary, recognize whether it belongs to any group of geometrically characteristic boundaries, provide boundary plane indices in coordinate systems of the first and the second grain. We can deal with both cubic and hexagonal close-packed polycrystals. We can also find all characteristic boundaries assuming certain misorientaion. For a given misorientations, such catalogues of characteristic boundaries are presented in the form of stereographic projections of boundary plane normals. We have used three different methods including analytical calculations, as well as purely numerical searches. Fortes decomposition and distance minimizations make it possible to directly introduce some uncertainties. Having several methods enables to perform various cross-checks which might be important for further investigations. Finally, obtained images can be linked to similar figures obtained experimentally.
