Texture is an important property especially for metallic materials having hexagonal close‐packed crystal structure. In order to understand the overall property or change in the microstructure of materials, neutron diffraction is a powerful tool of investigation. In this study, we attempt to measure the textures of Ti–6Al–4V (mass%) alloy by using a time‐of‐flight neutron diffractometer, iMATERIA. The results indicate that the texture measurement for the hexagonal phase is possible with the same method as for cubic metals. The texture of cubic β phase, whose volume fraction is several percent, can simultaneously be determined together with the hexagonal α phase.
