Investigation of glass forming ability of Al-based metallic glasses by measuring vaporization enthalpy.

ABSTRACT: The analysis of the enthalpy changes for vaporization (ΔH_vap) of Al-based metallic glass (MG) can provide insight into the origin of the MG's glass forming ability (GFA). The ΔH_vap of three Al-based MGs, Al_{84.5 ± x}(Y₁₀Ni_5.5)_{15.5 ± x}, Al_{85 ± x}(Y₈Ni₅Co₂)_{15 ± x}, and Al_{86 ± x}(Y_4.5Ni₆Co₂La_1.5)_{14 ± x}, (hereafter referred to as AYN_x, AYNC_x, and AYNCL_x, respectively), is analyzed by measuring their weight losses below their glass transition temperatures. The relationship between ΔH_vap and aluminum concentration exhibit minimum values in the range of 83-85 at.% of Al, and
