“…Such examples include low alloyed TRIP steels, [1][2][3][4] Q&P steels, 5,6) nano-bainite steels, [7][8][9][10] medium Mn steels, 11,12) etc. Hence, the characterization of the retained austenite is very important and many studies have been performed so far.…”

The austenite reverse transformation behavior in a 1.5Mn-1.5Si-0.2C steel was in situ monitored using dilatometry, electron back scatter diffraction (EBSD), X-ray diffraction and neutron diffraction. The austenite reversion kinetics showed excellent agreements between dilatometry and neutron diffraction, whereas the austenite formation was observed to start at much higher temperature in cases of EBSD and X-ray diffraction measurements. Such discrepancy in transformation temperature is attributed to the change in chemical compositions near the surface of a specimen heated to elevated temperatures either in vacuum (EBSD) or in a helium gas atmosphere (X-ray); Mn and C concentrations were found to decrease with heating. In situ neutron diffraction enables us to investigate the changes in lattice constants of ferrite and austenite, showing not only thermal expansion but also suggesting carbon enrichment and phase stresses during the decomposition of the retained austenite and austenite reversion upon heating.

Abstract:The neutron instruments suite, installed at the spallation neutron source of the Materials and Life Science Experimental Facility (MLF) at the Japan Proton Accelerator Research Complex (J-PARC), is reviewed. MLF has 23 neutron beam ports and 21 instruments are in operation for user programs or are under commissioning. A unique and challenging instrumental suite in MLF has been realized via combination of a high-performance neutron source, optimized for neutron scattering, and unique instruments using cutting-edge technologies. All instruments are/will serve in world-leading investigations in a broad range of fields, from fundamental physics to industrial applications. In this review, overviews, characteristic features, and typical applications of the individual instruments are mentioned.
