Because of large spot size and high penetrability, neutron diffraction can acquire the average orientation information of a bulk polycrystalline sample and monitor the microstructure and/or texture evolutions. Though many new neutron facilities with higher thermal beam flux have been established for residual stress and texture measurements, neutron diffraction facilities attached at a conventional research reactor like the Japan Research Reactor No.3 (JRR-3) are still being expected to support broader neutron diffraction application studies not limited by metals, alloys, ceramics, composite materials, and even geological materials. In this oral presentation, the newest experimental results from a round robin texture measurement test of international standard limestone will be formally reported and the related discussion and future prospect will be involved.
