Popis:	Microstructures formed as a result of multiple twinning have been simulated by means of computer modelling. Grain boundary misorientation (character) and triple junction distributions have been studied with the emphasis on the effect of initial texture and multiple twinning process. Although grain boundary distributions are similar in all the microstructures modelled, sharp initial texture leads to a somewhat enhanced amount of Σ3 boundaries and to a considerable increase in the number of triple junctions containing two Σ3 boundaries. The impact of these parameters on the material susceptibility to intergranular crack propagation has been analysed and implications for grain boundary engineering has been discussed.
