Room-temperature coefficient of thermal expansion of metals derived from the elastic constants

Abstract Room-temperature coefficients of thermal expansion (CTE), α, of 27 metals and 2 semi-metals (Si and Ge) are derived from elastic constants (Young modulus, shear modulus, Poisson’s ratio) coupled with a Debye treatment of the vibrating lattice. Theoretical values of αcalc show good agreement with the experimental ones.
