Magnesium and titanium based metals and alloys offer, due to their low density, an interesting alternative in lightweight applications. Their mechanical properties are strongly influenced by their hexagonal crystal lattice which provides only limited number of easy slip systems to accommodate plastic deformation. Therefore, deformation twinning is an important mechanism that has a crucial influence on mechanical processing of these materials. Despite its importance, the interactions of twins with microstructure (solute atoms, precipitates) are not fully understood. The topic of this project is the analysis of these interactions in binary and commercial alloys of magnesium and titanium using in-situ experimental methods and multiscale modeling within the framework of continuum mechanics and molecular dynamics. The applied techniques will complement each other in order to clarify an influence of microstructure on twin nucleation and propagation in a material. Obtained results can be useful in the development of future materials. |
