Abstract
Effect of vacancy formation energy and microhardness on the Debye temperature of some α-phase alloys have been carried out on α-phase (fcc phase) Cu1-x-Znx alloys. The Debye temperatures of α-phase Cu1-x-Znx alloys have been obtained from X- ray integrated intensities. The integrated intensities have been measured with a Philips 3020 powder diffractometer fitted with a proportional counter using filtered CuKα radiation at room temperature and have been corrected for thermal diffuse scattering. The Debye temperatures of these alloys have been estimated from the hardness and are compared with those obtained from specific heats, elastic constants and X-ray intensity measurements.
