Low-temperature molar heat capacities and inter-relations of thermodynamic properties of (copper + aluminium) alloys

摘要: Abstract The heat capacities of six alloys from (copper + aluminium) representing the α, γ2, δ, ζ2, η2, and θ phases which are stable at below 773 K have been measured between 6 300 quantities {So(298 K)−So(0)} {H o (298 K) −H (0)} T calculated. Assuming that configurations quenched those present K, entropies combined with other existing thermodynamic functions to evaluate configurational vibrational contributions. Inter-relations among standard enthalpies formation, entropies, volume changes explored, leading conclusion that, although quantitative relations may not be postulated, results indicate a correspondence exothermicity ordering approach atomic species on alloying.
