Sažetak
We start with a brief review of progress in research and applications of metallic glasses (MG) over last 60 years. The milestones, such as their discovery, fabrication of bulk MGs (BMG) and the progress in commercialization of MGs will be emphasized. Next, we briefly review early research of rapidly quenched alloys in Zagreb and fruitful collaboration in this research between Zagreb and Sarajevo (initiated by Professors B. Leontić and E. Girt in 1969.) We show that till 1990. the research and fabrication of MGs in Zagreb and Sarajevo was at the forefront of research in this field. This showed very clearly at the EC‐Yu Colloquium on Advanced Materials, held in September 1988. in Sarajevo. We compare some predictions from this Colloquium with the present achievements in the field of MGs. Further, we outline the impact of the discovery of BMGs in 90‐ties (at first in multicomponent and then in binary transition metal alloys) on the further development of this field of research . We will use binary BMGs (which are the base of more important multicomponent BMGs) in tackling still unsolved problem of the origin of high glass forming ability (GFA), which enables the formation of BMGs. Some largely ignored features of binary Cu‐Ti, Zr, Hf MGs, such as ideal solution behaviour are emphasized and their relation with GFA and formation of BMGs in Cu‐ Zr, Hf alloys is proposed. On the basis of previous results for Cu‐Zr MGs we propose a novel criterion for selection of potential BMG forming alloys, which may apply to multicomponent systems based on transition metals, too.
