“…it identifies which irradiation defects are present and precisely where they are located. Lastly, a set of dedicated MATLAB algorithms, called DefectQuant [3], were developed and tailored to extract quantitative information from each defect category with a full consideration of the matrix crystal structure, orientation and diffraction condition. All three steps of this new workflow were tested using a pair of pristine and neutron-irradiated HT-9 (a 12Cr tempered martensitic alloy) specimens neutron irradiated to 111.8 dpa that contained a high density of extended defects.…”
