Laser induced breakdown spectroscopy (LIBS) calibration curves for ZrSn alloys were obtained. Relationships between the atomic emission lines present in the spectra and the Sn concentration of the samples showed a linear behavior. Also Zy-2 standards

Zirconium and its alloys are widely used in the nuclear industry. Under normal conditions, Zr-alloys are polycrystalline and contain a high density of grain and interphase boundaries. These boundaries function as paths for accelerated matter movement

U bulk diffusion in a-Zr was measured by mean a-spectrometry in the temperature range 763?1123 K(540?850 C). A deviation from the Arrhenius law consistent in a downward curvature was observed;such anomaly is similar to the self and hetero substitutio
