Metallic glasses (MGs) look like metals and have the intimate structure and sometimes the behavior of glasses. The first reported scientifically obtained MG was the alloy Au75Si25 produced at Caltech by Klement et al., in 1959, by extremely rapid cooling of the Au-based melted alloy. Due to the high solidification rate required to produce MGs, the section thickness was small, i.e. only a few tens of micrometers, typically 20 to 50m [5-7].

Highlights FeSiBAlNi (C, Ce) amorphous HEAs have been fabricated by mechanical alloying. The effects of C and Ce addition were investigated. Ce addition exhibits a remarkably enhanced effect on glass forming ability (GFA). C and Ce additions are beneficial to enhance thermal stability. http://www.sciencedirect.com/science/article/pii/S0304885316303894

We study the effect of graphene (Gr) addition on the amorphisation and thermal stability of the Al88Ni6Y6 + x wt.% Gr (x = 0, 0.2, 0.5, and 0.8) alloys during mechanical alloying. The final milling-products consist of the amorphous phase and a few nanocrystals with face-centered cubic (fcc)structure, and the AlNiY(Gr) amorphous composites have been fabricated. We find that the 0.2 wt.% Gr addition obviously benefits the amorphisation and remarkably
