The dislocation microstructure developing during neutron irradiation is determined by X-ray line profile analysis.
During neutron irradiation of metals, owing to the enhanced number of vacancies and interstitial atoms, the climb motion of disloc

Specimens of cold-rolled zirconium were tensile-deformed along the rolling (RD) and the transverse (TD) directions. The stress-strain curves revealed a strong texture dependence. High resolution X-ray line profile analysis was used to determine the p

Nanocrystalline materials reveal excellent mechanical properties but the mechanism by which they deform is still debated. X-ray line broadening indicates the presence of large heterogeneous strains even when the average grain size is smaller than 10
