“…In the final crystallization, namely 0.93 < α , all Avrami exponent curves rapidly increase from 3.4 to 4.0. The reason for this could be second crystallization phase precipitated form matrix . It can be seen that the Avrami exponent n (α) becomes greater with increasing annealing temperature, which suggests that crystallization evolution is faster at higher annealing temperature.…”

The crystallization kinetics of Cu55Zr45 (at%) glassy alloy is studied under isothermal condition using differential scanning calorimetry (DSC). The plot of correlation between the crystallized volume fraction α and annealing time t shows a sigmoid‐type curve, which is steeper with higher annealing temperature. Furthermore, in isothermal crystallization condition, local activation energy Eα values, determined using the Arrhenius equation, range from 181.1 to 187.8 kJ/mol, which is nearly a constant. The local Avrami exponent n(α) values, obtained by the Johnson‐Mehl‐Avrami equation, which range from 2.2 to 4.0 at different annealing temeperatures, which indicates that the crystallization mechanism is diffusion‐controlled transformation. Moreover, n(α) becomes greater with increasing annealing temperature, which indicates that annealing temperature can affect nucleation rate and growth type.

“…where "β" stands for heating rate, "T" stands for characteristic temperature, "E" stands for activation energy of crystallization at T, "R" stands for universal gas constant (8.314 J mol À1 k À1 ) and 'C' is a constant. [128][129][130][131][132][133] The activation energy required for the initiation of first-stage crystallization for most of the Al-based glassy alloys lie in the range of 140-320 kJ mol À1 . [134] Presence of nanocrystalline phases in the amorphous matrix act as nucleation sites and assists in devitrification process and thus decreases the transition temperatures and related activation energies of crystallization.…”

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.
