The hardness and electrical conductivity of Cu-Zr and Cu-Zr-Si alloys varying with differ- ent aging regimes were measured and the factors influencing the electrical conductivity were analysed.It is believed that a little Si can refine the precipitates and improve the resistance to softening.The improvement of materials properties by aging and the effect of cold work were also discussed.

The activities of In in two pseudo-binary systems of fixed molar fraction ratio N_(Bi)/N_(Ti) have been measured by means of EMF method using zirconia solid electrolyte gal- vanic cells over the temperature range of 973—1223 K.The excess free energies were deter- mined based on the experimental data.The experimentally determined thermodynamic prop- erties of the ternary alloys agree well with the values caleulated from the author's equations using related binary data.The excess free energies are negative in almost all compositions ex- cept those near the In-Tl side and become negatively larger as the compositions approach the Bi-Tl side.
