Abstract
Micrometer to centimeter scale analyses of the crystalline phase volume fractions in a trip- assisted duplex stainless steel were performed as a function strain using electron backscatter diffraction (EBSD), in situ neutron diffraction, and energy selective neutron imaging (ESNI) methods. In contrast to the localized investigations of EBSD, ESNI provides macroscopic spatial distributions in a volume-averaged manner over the entire specimen with a spatial resolution of about 65 µm. The ESNI shows that the martensite phase is concentrated on the necking region and estimates the martensite volume fraction of 14 % at a strain of 0.2, which is comparable to the in situ neutron diffraction result.
