Neutron Strain Scanning of Duplex Steel Subjected to 4-point-Bending with Particular Regard to the strain Free Lattice Parameter D-0
Original language description
Neutronographic residual stress analysis on multiphase materials is challenging with regard to phase-specific micro residual stresses and to the consideration of an appropriate stress free lattice parameter for meaningful lattice strain calculation. Even in case of randomly textured materials stress analysis becomes more elaborate due to plastic anisotropy effects. According to literature for stress analysis using neutron diffraction lattice planes should be chosen that are less prone to plastic anisotropy. These are the {311} austenite and the {220} ferrite planes in case of duplex steels. Here, we report about phase-specific in-situ neutron strain scanning at SALSA@ILL, Grenoble during defined 4-point-bending of duplex steel X2CrNiMoN22-5-3 using exactly these two recommended diffraction lines. It is shown that due to the local texture of the bending bars, which was cut from a hot rolled cylindrical rod, strong plastic anisotropy was determined. This effect must be taken into account for diffraction based residual stress analysis to prevent from erroneous stress determination.
