| Riassunto: | Заглавие с экрана Hydride-forming alloys of the Zr-Nb-H system are analyzed. In the initial state in the Zr-2.5Nb alloy, particles of the Nbβ phase are observed in the bulk and at the grain boundaries. In addition to the main Zrα phase, the Nbβ phase appears in the Zr-2.5Nb-0.19Н alloy and precipitations of ZrН and ZrН2 hydrides are also observed. The microhardness of the Zr-2.5Nb alloy samples is (130±7) HV, and after hydrogenation this value rises by 1.3 times, up to (166±7) HV. The value of the yield strength for both samples is comparable within the error values. The value of the tensile strength for the hydrogenated sample is 4.3% higher than for the original sample. For a sample with 0.19 wt. % hydrogen, value of deformation to failure is 2.1% less compared to the original sample not containing hydrogen. |
