Abstract

The specific heat values of liquid Pd₄₀Cu₃₀Ni ₁₀P₂₀, Pd₄₀Ni₄₀P₂₀ and Pd₄₀Cu₃₀P₂₀ alloys which are known to show excellent glass forming ability have been measured in the temperature range between 973 and 1123 K by the heat-flux type DSC with triple cells. The uncertainty of the specific heat values obtained with the DSC was estimated to be ±7% at most by measuring the specific heat of pure silver. The specific heat values for liquid Pd₄₀Cu₃₀Ni ₁₀P₂₀, Pd₄₀Ni₄₀P₂₀ and Pd₄₀Cu₄₀P₂₀ alloys are given as follows, (unit: C_p: Jg^-1 K^-1, T: K) C _{pPd40Cu30Ni10P20}× = -2.45 × 10^-4 T + 0.739 973 ≤ T ≤ 1123 C_pPd40Ni40P20 = -2.53 × 10^-4 T + 0.727 1023 ≤ T ≤ 1123 C_pPd40Cu40P20 -4.18 × 10 ^-4 T + 0.828 973 ≤ T ≤ 1123.
