Abstract
X-ray measurements of the lattice parameters have been made in four Cu-Ga alloys in the solid-solution range using a Unicam 19 cm high-temperature camera in the temperature interval of 30-514 DegreesC. The measured lattice parameters have been found to increase non-linearly with the temperature and this variation has been expressed in an analytical form from least-squares fitting. The linear thermal expansion coefficients have been found to decrease with increasing temperature in these alloys with a tendency to attain a nearly constant value at higher solute concentrations, and the decrease is rather slow compared to that observed earlier with Ag-Ga alloys over the same range of temperature.
