An in situ neutron diffraction experiment during cyclic tension-compression with an applied strain of 0.01 and was conducted at room temperature using a MgZnY alloy, after hot-extrusion at 723 K with the extrusion ratio of 10, to understand the deformation behavior of both Mg and LPSO phases and to elucidate kinking in the LPSO phase including its effect to the strength during the cyclic tension-compression deformation. The evolutions of textures, lattice strains of individual constituent phases measured from neutron diffraction will be plotted with the applied stress, strain and the cyclic number, and details will be presented in this presentation.
