Effect of hydrogen on the phase–structure transformations in ZrCrNi alloy
The effect of hydrogen—Hydrogenation, Disproportionation, Desorption, Recombination (HDDR) process—for the ZrCrNi alloy on its phase–structure transformations was investigated by means of differential thermal analysis (DTA) and X-ray diffraction (XRD) at the initial hydrogen pressure ∼5.0 MPa and th...

| description | The effect of hydrogen—Hydrogenation, Disproportionation, Desorption, Recombination (HDDR) process—for the ZrCrNi alloy on its phase–structure transformations was investigated by means of differential thermal analysis (DTA) and X-ray diffraction (XRD) at the initial hydrogen pressure ∼5.0
MPa and the temperature range from room temperature to 970
°C. The hexagonal C14 (MgZn
2) type Laves phase is the main phase of the alloy. Besides the peak of hydrogen absorption at room temperature, two exothermic (at 535 and 675
°C) and two endothermic (at 791 and 819
°C) effects were determined by DTA during heating of the ZrCrNi–H
2 system. The decomposition (disproportionation) of hexagonal C14 type Laves phase started at the initial hydrogen pressure
