X-Ray Debye temperature study of Gruneisen constant of Hexagonal Phase Cu_1-x-Zn_x alloys

Abstract

Hexagonal Close Packed (HCP) phase Copper-zinc (Cu1-x Znx) alloys have been discussed with compositions (x = 79.20, 82.00, 84.30, 86.10, 97.10, 97.50, 98.10, 98.60, 99.50). These alloys have been prepared from spectroscopically pure copper (Cu) and zinc (Zn) metals by melting using the glass blowing and vacuum sealing process with appropriate quantities in evacuated quartz tubes. For the duration of melting process the alloy/mixture was systematically stirred to get homogenization alloy. The powder samples of all the Cu1-x Znx alloys were prepared by gently filing the ingots with jeweller’s file. The evaluated Debye temperature values were compared with Debye temperature values evaluated from Kopp-Neumann relation and other four relations composition dependence relation, specific heat relation, empirical relation, Gril and Mittra relation. Gruneisen constant of hcp phase Cu1-x-Znx alloys were evaluated utilizing a relation associated with Debye temperature values were measured from X-Ray diffraction method.
