摘要: Fractional concentrations of indium solutes at Gd sites and Al in the Laves phase Gd113xAl223x were measured for different temperatures sample compositions using perturbed angular correlation spectroscopy. At fixed composition, fraction on was observed to decrease as temperature increased. temperature, increase composition became more deficient Gd. The trends are explained a thermodynamic model that couples solute site occupation with point defects. enthalpy crystal when switches from an determined be 0.343~7! eV.
