Özet

The variations of thermal conductivity with temperature for Bi-[x] at.% Zn-2 at.% Al alloys (x= 4.5, 18.0, 30.1, 79.0 and 98) were measured by using a radial heat flow apparatus. From the graphs of thermal conductivity versus temperature, the thermal conductivity of solid phases at their melting temperature for Bi-[x] at.%Zn-2 at.% Al alloys (x= 4.5,18.0,30.1, 79.0 and 98) were obtained. Dependency of the thermal conductivity on composition of Zn in the Al-Bi-Zn alloys was also investigated. According to present experimental results, the thermal conductivity of the Bi-[x] at.% Zn-2 at.% Al alloys linearly decrease with increasing the temperature and exponentially increase with increasing the composition of Zn.
