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 <...

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 different from those in close-packed crystals. The biggest mystery is the occurrence to Tresca inapplicable to bcc metals. While it is frequently seen in tensi...

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 transition meta...
