Description:

The Matlab toolbox STABiX provides a unique and simple way to analyse slip transmission in a bicrystal. Graphical User Interfaces (GUIs) are implemented in order to import EBSD results, and to represent and quantify grain boundary slip resistance. Key parameters, such as the number of phases, crystal structure (fcc, bcc, or hcp), and slip families for calculations, are set by the user. With this information, grain boundaries are plotted and color coded according to the m' factor that quantifies the geometrical compatibility of the slip planes normals and Burgers vectors of incoming and outgoing slip systems. Other potential functions that could assess the potential to develop damage are implemented (e.g. residual Burgers vector, N factor, resolved shear stress, misorientation...).

Furthermore, the toolbox provides the possibility to plot and analyze the case of a bicrystal, and to model sphero-conical indentation performed in a single crystal or close to grain boundaries (i.e. quasi bicrystal deformation). All of the data linked to the bicrystal indentation (indenter properties, indentation settings, grain boundary inclination, etc.) are collected through the GUI. A pythonTM file can be then exported in order to carry out a fully automatic 3D crystal plasticity finite element simulations of the indentation process using one of the constitutive models available in DAMASK. The plasticity of single crystals is quantified by a combination of crystal lattice orientation mapping, instrumented sphero-conical indentation, and measurement of the resulting surface topography. In this way the stress and strain fields close to the grain boundary can be rapidly assessed. Activation and transmission of slip are interpreted based on these simulations and the mechanical resistance of grain boundaries can be quantified.
