Název v původním jazyce

In situ neutron diffraction study of alpha-gamma Fe-Cr-Ni alloys under tensile deformation.

Popis výsledku v původním jazyce

Neutron diffraction experiments were performed in situ upon tensile loading for five Fe-Cr-Ni alloys with different ferrite volume fractions ranging from 0 to 100%. The diffraction profiles were recorded along with the tensile deformation curves during temporary stops in a deformation machine (5 ks each) with the crosshead fixed. One reflection of each phase, (111) of austenite (gamma) and (110) of ferrite (alpha), respectively, were measured simultaneously byusing a position sensitive detector. Evolution of elastic lattice strains and dislocation densities in both constituent phases was evaluated from measured diffraction profiles as a function of external loading. Based on these experimental results, heterogeneous deformation behavior in the alpha-gamma dual-phase alloys is discussed.
