Specific volumes of the Zr41.2Ti13.8Cu12.5Ni10.0Be22.5 alloy in the liquid, glass, and crystalline states

Abstract

The specific volumes of the Zr41.2Ti13.8Cu12.5Ni10.0Be22.5 alloy as a function of temperature, T, are determined by employing an image digitizing technique and numerical calculation methods applied to the electrostatically levitated spherical alloy. The linear fitting of the volumes of the alloy in the liquid, Vl, glass, Vg, and crystalline Vc, states in the temperature ranges shown in parentheses are Vl(T)=0.1583+8.877×10−6T(cm3/g) (700–1300 K);Vg(T)=0.1603+5.528×10−6T (400–550 K);Vc(T)=0.1583+6.211×10−6T(400–850 K). The average volume thermal expansion coefficients within the temperature ranges are determined to be 5.32, 3.39, and 3.83×10−5 (1/K) for the liquid, glass, and crystalline states, respectively.
