The analysis of structure and defective substructure rail steel in uniaxial compression to a degree 50% is carried out. It revealed that cold hardening has multi-stage character accompanied by fragmentations pearlite grains which field as the deformation increases reaches ≈ 0.4 volume foil studied at ε = 50%. fragments being formed ferrite plates are separated low-angle boundaries. average size...

Nanoporous metals produced by dealloying have aroused enormous interest due to exotic mechanical and physico-chemical properties that are usually inaccessible in their bulk form. Interestingly, when binary solid-solution alloys, such as Ag–Au dealloyed, the resulting nanoporous inherit crystal structure of parent alloys. In this Letter, we examined evolution during Fe–Rh alloys show single-phas...
