Zusammenfassung: | We consider main conditions of the adequate estimation of degradation of mechanical properties of chromium-nickel alloys in gaseous hydrogen. We establish that evacuation is a necessary procedure for preparing a working chamber for testing. The low-cycle fatigue and relative contraction are the most sensitive to hydrogen embrittlement. We determine the strain rate and hydrogen pressure that maximally impair mechanical properties. [Materials include: 12Kh18N10T, KhN55MBYu, KhN70MBYu.] |
