The enthalpies of formation at 640Β°C of solid Ni-Cu and Ni-Au alloys have been measured as a function of composition by means of a differential solution calorimeter. Both systems are characterized by positive heats of formation. The conoentration variations of the partial molar heats of solution of

## Abstract The directional crystallization of eutectic Alο£ΏNi alloys was studied. Variations of the growth rate caused significant change of the microstructure and mechanical behaviour of eutectic alloys. On the base of a Tiller's analysis involving the voluminal ratio of the two phases the interph
