“…[55,33] average atomic size or overall mixing enthalpy are affected. Replacing Ni in the Al 85 Ni 9 La 6 alloy with Cu also decreases its thermal stability [90]. Small amount of Si affects crystallization of Al 86 Ni 2 Co 5.8 Gd 5.7 alloy [91].…”

International audienceIn the present work, we discuss the glass-forming ability of various binary alloys in which the glassy phase was not formed even by melt spinning technique with high cooling rate of the melt up to 1 MK/s (some consisted of partly glassy phase), though by commonly accepted guidelines, these alloys could be as good glass-formers as many other binary glasses. The alloys studied belong to binary systems with multiple eutectics; the constituent elements have a negative enthalpy of mixing, and a significant variability of atomic size differences is observed from system to system. The results indicate the necessity of taking into account simultaneously various factors influencing the glass-forming ability including melt fragility

“…The primary phases of the alloys are also listed in Table 1. Such results indicate that replacing Ni by Co in the Al-Ni-La alloys promotes the precipitation of the metastable phase(s) in the first reaction, being different from replacing Ni by Cu where precipitation of single fcc-Al as the primary phase is promoted [13].…”

“…However, sometimes the difference in diffusion rate is not the main factor. It has been revealed that replacing Ni by Cu with a larger radius of 1.28 Å can promote the precipitation of single fcc-Al as the primary phase [13].…”

“…La atoms also have strong interaction with Cu atoms as evaluated by the calculated enthalpies of solution at infinite dilution, DH AB [19]. The more negative the DH AB is, the larger the atomic constraint force is, and the higher the thermal stability is [20]. According to the Miedema equation [21]: Table 1.…”
