| Abstract: | Based on the expression of pressure at temperature T and in terms of the universal equation of state Debye model and the thermedynamic relations,a general expression for the cal-cutation of the linear thermal expansion coefficients of metals is obtained. This formula applied to the calculation of Al,Cu,Pb. Calculated results are in good agreement with the experiments. |
