“…[ 61 ] Bond shortening of Al with its nearest neighbor Ag, Au, and Pt atoms has been reported in case of Al 86 Ni 7 X 1 Y 6 (X = Ag, Au, Pt) amorphous alloys. [ 62 ] Similarly, Fe–Al bond shortening was observed in Al 90 Fe x Ce 10− x glassy ribbons. [ 63,64 ] The bond shortening effect is ascribed to hybridization of s–p orbitals of Al and d ‐orbitals of TM.…”

“…For example, there are cases where fully amorphous Al–TM–RE systems could be obtained with λ < 0.1, because of effect of bond shortening arising from the interaction between Al and TM. [ 60–66 ] In case of Al 89 La 6 Ni 5 glassy ribbons, Ni–Al bond shortening of ≈4.5% has been observed. [ 60 ] Zalewski et al have reported Al–TM bond shortening of 10% in various Al–TM (Ni and Co)–RE (Y and Sm) amorphous ribbons.…”

“…[ 63,64 ] The bond shortening effect is ascribed to hybridization of s–p orbitals of Al and d ‐orbitals of TM. [ 60–66 ] The atoms in the amorphous alloy systems cannot always be considered as hard spheres due to this effect or in other words, and calculation by taking nominal atomic radii leads to error in many cases. Thus, Zhang et al further modified the “ λ criterion” by replacing nominal atomic radii (

r_{i}

) in Equation () with effective atomic radii (

r_{i}^{\text{eff}}

) and introduced λ ‐prime ( λ ′) criterion.…”

Aluminum‐based glassy alloys and composites exhibit more than two times higher tensile and compressive strength and superior corrosion resistance compared to the conventional Al alloys. However, the low glass‐forming ability (GFA) of Al‐based glass‐forming compositions restricts the synthesis of large dimension Al‐based amorphous alloys. In contrast, powder metallurgy route leads to synthesis of higher‐dimension Al‐based metallic glasses and composites. A detailed review on the efforts made to improve the dimension and mechanical properties of the Al‐based glassy alloys and composites is essential to further develop these materials for industrial applications. Researchers aspiring to develop high‐strength light‐weight materials can be benefited from such a detailed review on Al‐based amorphous alloys and composites. In this review article, a holistic approach is made to understand the GFA, crystallization behavior, corrosion resistance, and mechanical and electronic properties of Al‐based glassy alloys and composites. The effects of various alloying elements on GFA and criteria to optimize Al‐based glass‐forming alloy composition are discussed. The crystallization behavior is discussed with phase‐separation and quenched‐in nuclei models. The effects of various crystalline phases in the amorphous matrix on corrosion resistance and mechanical and electronic properties are discussed in detail.

“…Because of the Al-TM "bond shortening" effect from the strong interaction between Al and TM, atoms in alloys cannot always be treated as hard-spheres [66]. In Al 86 Ni 7 X 1 Y 6 (X: Ag, Au, Pt), a similar "bond shortening" effect is also observed in the Al-X bond [67]. The nominal atomic radii are replaced by the effective atomic radii, resulting in a revised λ` parameter.…”

The main recent advances in Al-based amorphous alloys are discussed in three areas: crystallization behavior, glass-forming ability and minor alloying effects. First, as a brief introduction, the special features and structure-property relationships are presented for the Albased amorphous alloys. The different models for the nucleation behaviors, such as phase separation model and the quenched-in nuclei model, are compared and evaluated. In addition, an overview is given for the effects of minor alloying additions on glass-forming ability (GFA) and the crystallization behavior in terms of the reported structural, thermodynamic, kinetic factors.
