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 (γ) and (110) of ferrite (α), respectively, were measured simultaneously by using 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 α-γ dualphase alloys is discussed.

In situ neutron-diffraction technique has been employed to study the uniaxial tensile deformation of a bulk nanocrystalline Ni-Fe alloy. In contrast to an increase in the full-width half-maximum (FWHM) of the neutron-diffraction patterns for the coarse-grained Ni, the FWHM for the nanocrystalline Ni
