Project

The model of dislocation structure formation based on the theory of continuous distribution of dislocations (GA106/00/1109)

theoretical model of the dislocation structure formation and their transformations of dislocations. Twaveraged interacting dislocation populations are considered. The glide dislocations are described by the di...

Non-Schmid behavior of dislocations in magnesium and its alloys (8J19UA037)

The aim of proposed project is the computer simulation study of dissociated dislocations in magnesium. It is supposed that processes in dislocation core can lead to inclinations from the Schmid law for dislocation glide, si...

The continuum mechanics approach to the problem of geometrically necessary dislocation boundaries (GA106/03/0826)

At medium and large plastic strains dislocations commonly organize themselves into a mosaic pattern of thin boundaries that surround regions almost dislocations free, Due to differing slip activity the regions on either side of a

Reactions of slip dislocations with grain boundary observed by in situ TEM and their relation to slip band structure near grain boundary in bulk (IAA1010702)

at the GBs and GB dislocation structure are most important. The slip continues from new dislocation sources rather than by direct transmission of slip dislocations. The aim of this project is to detect the reasons for the ...

Interaction of slip dislocations with grain boundaries observed by in situ TEM and in situ X-ray topography in Fe-Si bicrystals (GA202/98/1281)

The aim of this project is to study the interaction of slip dislocations to detectthereasons for impeding the slip dislocations at the grain boundaries and their possible to follow dynamically the interaction of single dislocati...
