Description	In situ neutron diffraction experiments during tension-compression deformation were performed on five Fe-Cr-Ni alloys with the volume fraction of ferrite (alpha) ranging from O.O to 100%, Tensile deformation was applied in a step by step manner up to a strain of 1.3-2.0% followed by compressive deformation, and neutron diffraction spectra were recorded during temporary stops of a deformation machine with fixed crosshead. (111) reflection of austenite and (110) of ferrite, respectively, were measured simultaneously by using a position sensitive detector. Elastic lattice strains in both constituent phase were evaluated from measured diffraction spectra as a function of external load, Based on these experimental results, heterogeneous deformation behavior in the aplpha gamma dual phase alloys is discusedconsidering the Bauschinger effect. It is consluded that large compressive residual lattice strains detected in the gama phase after tencile pre-straining, causes the large Buschinger effect in alpha-gamm In situ neutron diffraction experiments during tension-compression deformation were performed on five Fe-Cr-Ni alloys with the volume fraction of ferrite (alpha) ranging from O.O to 100%, Tensile deformation was applied in a step by step manner up to a strain of 1.3-2.0% followed by compressive deformation, and neutron diffraction spectra were recorded during temporary stops of a deformation machine with fixed crosshead.
