Abstract EN
In the present investigation, thermal conductivity of Cu-Cr-Zr-Ti alloy was determined as the product of the specific heat (Cp), thermal diffusivity (α), and density (ρ) in the temperature range of 300–873 K.
The experimental results showed that the thermal conductivity of the alloy increased with increase in temperature up to 873 K and the data was accurately modeled by a linear equation.
For comparison, thermal conductivity was also evaluated for OFHC copper in the same temperature range.
The results obtained were discussed using electrical conductivity and hardness measurements made at room temperature.
Transmission electron microscopy (TEM) was done to understand the microstructural changes occurring in the sample after the test.
Wiedemann-Franz-Lorenz law was employed for calculating electronic and phonon thermal conductivity using electrical conductivity.
On the basis of studies conducted it was deduced that in situ aging may be one of the reasons for the increase in thermal conductivity with temperature for Cu-Cr-Zr-Ti alloy.
