In situ neutron diffraction during tensile straining of fine grained ferrite-pearlite steel

Original language description

Situ neutron diffraction during tensile deformation was performed on a steel with ferrite grain size 3.6 mum, which was close to the achievable minimum size for a ferrite-pearlite structure. The lattice plane strain, microstrain related to dislocation density, and the size of coherently diffracting blocks related to dislocation cell size were determined from the profile analysis of (110) diffraction spectra, as a function of the applied stress. The change in lattice plane strain revealed that grain refining strongly influences 'grain to grain yielding' behaviour with respect to Luders deformation. The increase in dislocation density estimated in the uniformly extending regime was similar to that observed in another specimen with ferrite grain size 46.2mum

Neutronové difrakční studie jemnozrnné fericko-perlitické oceli in situ v průběhu tahové deformace

Czech description

Neutronový difrakční experiment byl proveden in situ v průběhu tahové deformace na vzorcích oceli s velikostí feritického zrna asi 3.6 mikrometru. Velikost mřížové deformace, mikrodeformace v důsledku změn dislokační hustoty a střední velikost subzrn v závislosti na stupni deformace byly určeny z analýzy difrakčního profilu 110.
