Hi Vinod,
if you are looking for a k=f(T), I suggest a piecewise linear or polynomial in which you can define the function that links conductivity and temperature Regards

Piece-wise linear will give you a more stable solution.

Try searching something with Google, for example this:
http://www.nist.gov/data/nsrds/NSRDS-NBS-8.pdf or some book like this: "Correlations for the Thermal Conductivity of Metals as a Function of Temperature" S. I. Abu-Eishah Regards
