[Abstract]:Amorphous alloys have obvious advantages over traditional crystalline alloys in mechanical properties, wear resistance and corrosion resistance, magnetic properties, etc. They are a new class of structural and functional materials with good application prospects. The interaction of amorphous alloys with hydrogen can produce many interesting physical and chemical phenomena and applications. In this paper, the research progress on the interaction between amorphous alloys and hydrogen is reviewed from the aspects of physical basis and material application. In physical basic research, the dissolution of hydrogen in amorphous alloys is discussed from the point of view of the existing state of hydrogen in amorphous alloys. The effects of hydrogen on the thermal stability, magnetism, internal friction and hydrogen embrittlement of amorphous alloys are analyzed. In the aspect of material application, hydrogen absorption improves the plasticity and glass-forming ability of amorphous hydrogen storage alloy, amorphous alloy hydrogen functional film, hydrogen induced amorphous alloy. The progress in the preparation of nanocrystalline hydrogen storage materials using amorphous alloys is reviewed. Finally, the research and application of the interaction of amorphous alloys with hydrogen are summarized and prospected.
