| Summary: | Заглавие с экрана In this work new multicomponent Nb–Ni–Ti–Zr–Co alloys were synthesized. There were made one equimolar alloy (Nb20Ni20Ti20Zr20Co20) and two non-equimolar alloys with low and high Nb content (Nb15Ni20Ti15Zr30Co20 and Nb74Ni6Ti9Zr5Co6 respectively). It was observed that equimolar alloy consisted only BCC phases such as BCC-(Nb, Ni, Ti, Zr, Co) and BCC-Nb(Ni, Ti, Zr, Co). Nb20Ni20Ti20Zr20Co20 alloy had the highest concentration of equimolar phase (84 vol. %) and Nb74Ni6Ti9Zr5Co6 alloy had the highest concentration of Nb-rich BCC phase (95 vol. %). It was shown that alloy with low Nb content and equimolar alloy demonstrated high hydrogen permeability at 400 °C. Also, alloys had high resistance to hydrogen embrittlement, while high Nb content alloys are strongly susceptible to embrittlement. Thus, Nb15Ni20Ti15Zr30Co20 and Nb20Ni20Ti20Zr20Co20 are promising alloys for hydrogen purification membranes Текстовый файл |
