Project

Origin and mechanism of anomalous slip in non-magnetic bcc metals (GA16-13797S)

Plastic deformation of bcc metals is governed by processes that are very to Tresca inapplicable to bcc metals. While it is frequently seen in tension for the VB-group metals it only exists under compressio...

Calculation of the Peierls barrier in bcc metals and its dependence on stress (GAP204/10/0255)

Plastic deformation of bcc metals is governed by motion of 1/2 screw dislocations that possess a high lattice fiction (Peierls) stress. At finite temperatures the mixed metallic and covalent character of bonds in bcc

Interplay of plasticity and magnetism in alpha-iron and chromium (GA19-23411S)

Ferromagnetic alpha-Fe and antiferromagnetic Cr crystallize in the body-centered cubic (bcc) structure that exhibits internal magnetic order. This non-close on the plastic behavior of these metals has never been elucidated. The aim ...

Crack induced slip processes and stresses in bcc iron (KJB200760802)

Our project concerns crack stability in bcc iron. In this field we have already performed two experiments on single crystals of Fe(3wt.%Si) with edge cracks (001)[110], (-110)[110] and corresponding molecular dynamic (MD) simulations in 3D <...

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, similar to the situation in <...
