Przedstawiono wyniki badań termodynamicznych i mikroskopowych stopów Bi-Cu-Ni-Sn-Ti. Aktywność bizmutu w ciekłych, rozcieńczonych stopach w temperaturze 1373 K wyznaczono metodą równowagowego nasycania. Współczynnik aktywności bizmutu opisano równaniem Wagnera. Metodą najmniejszych kwadratów wyznaczono wartości parametrów oddziaływania poszczególnych składników stopu na aktywność bizmutu. Badania...
The urgent need of finding new, non toxic, high temperature solders induced the research of multicomponent systems, in order to find new materials that could substitute lead-containing solders. This work presents results of thermodynamic research of Cu-Ni-Sn-Ti-Zn system regarding Zn activity measurements by means of the vapour saturation method and the microstructure investigation by means of scanning...
