Paper Abstract

The work presents the study and crystallogeometrical analysis ofthe geometry of micro- and macrocracks in Ti3A1 single crystal with an orientation where the basal slip is operative. The structure of the core of a 1/6 <1120 > superpartial dislocation in the basal and prism planes is studied by computer simulation. A model for shear microcrack nucleation with screw a- superdislocatios interacting in the slip band of basal planes was suggested. The macrocracks path behaviour in Ti3A1 single crystal is discussed on the basis of the model proposed.
