On the origin of cementite diffraction peak broadening during tensile deformation at ambient temperatures

Helena Van Swygenhoven, Steven Van Petegem, Michael Andreas Weisser

We report on the diffraction peak shape evolution from cementite particles in three steel microstructures, recorded during in-situ tensile deformation at room temperature. We demonstrate that in a bainitic tempered steel the observed peak broadening and as ...

Two strain-hardening mechanisms in nanocrystalline austenitic steel: An in situ synchrotron X-ray diffraction study

Helena Van Swygenhoven, Steven Van Petegem, Patrick Schloth, Michael Andreas Weisser

The mechanical behaviour of nanocrystalline austenitic steels with and without yttria particles was investigated using in situ synchrotron diffraction during tensile deformation. Two different strain-hardening regimes were found. The first regime can be as ...

In situ room temperature tensile deformation of a 1% CrMoV bainitic steel using synchrotron and neutron diffraction

Helena Van Swygenhoven, Steven Van Petegem, Michael Andreas Weisser

Neutron and synchrotron X-ray diffraction spectra have been acquired during room temperature tensile deformation of a creep-resistant bainitic 1% CrMoV steel, in order to study the evolution of internal microstresses and load-sharing mechanisms between the ...
