X-Ray Determination of the Debye-Waller Factors and Debye Temperature In Hexagonal Cu1-X-Znx Alloys

E. Purushotham

The anisotropic Debye-Waller factors and Debye temperatures of zinc rich Cu1-x Znx alloys have been obtained from X-ray intensities. The intensities have been measured with Philips 3020 diffractometer fitted with a proportional counter using filtered Cukα radiation at room temperature and have been corrected for thermal diffuse scattering. The anisotropy observed in the values of Debye-Waller factors of hexagonal zinc rich Cu1-x Znx alloys conform to the trend observed in the anisotropy of Debye-Waller factors of hexagonal metals. The Debye temperatures obtained in the present investigation have been compared with the values of Debye temperature calculated from Kopp-Neumann relation.
