    Author : Tuerdi Maimaitiyili; Lund University.; Lunds universitet.; Malmö University.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in situ phase transformation; hydrogen embrittlement; hydrogen charging; zirconium hydride; γ-ZrH; synchrotron X-ray diffraction; neutron diffraction; hydrogen induced degradation; NATURAL SCIENCES; NATURVETENSKAP; Sciences; Zirconium hydride; phase transformation; in-situ hydrogen charging; hydrogen related degradation;

    Abstract : Zirconium alloys are widely used in the nuclear industry because of their high strength, good corrosion resistance and low neutron absorption cross-section. However, zirconium has strong affinity for hydrogen, which may lead to hydrogen concentration build-up over time during a corrosion reaction when exposed to water. READ MORE

    Abstract : Popular Abstract in English Zirconium alloys are widely used in nuclear power reactors as cladding material for their fuels due to the high strength, good corrosion resistance and low neutron absorption cross-section, even in extreme environment, that is characteristic for zirconium. The element, however, also has strong affinity for hydrogen, and when both are present they readily react and form a family of compounds called hydrides. READ MORE
