Identification and characterization of a new zirconium hydride

Zirconium alloys are currently used in nuclear power plants where they are susceptible to hydrogen pick-up. Hydride precipitation may occur when the hydrogen solubility limit is reached. Various Zr hydride phases, γ, δ and ε have been identified since the 1950s. Combining electron precession microdi...

Summary:Zirconium alloys are currently used in nuclear power plants where they are susceptible to hydrogen pick-up. Hydride precipitation may occur when the hydrogen solubility limit is reached. Various Zr hydride phases, γ, δ and ε have been identified since the 1950s. Combining electron precession microdiffraction, electron energy loss spectroscopy and ab initio electronic calculations, a new Zr hydride named ζ has been identified and characterized. It belongs to the trigonal crystal system with space group P3 m1 and it is fully coherent with the αZr matrix.
