摘要	The subsolidus phase relations of the Cu-Ga-N system are studied by X-ray powder diffraction. The phase relations of the binary Cu-Ga system are checked firstly. theta-CuGa2 which belongs to the tetragonal system is determined to be a stoichiometric compound and its thermal expansion is measured by temperature-dependent X-ray powder diffraction from 93 to 523 K. The linear temperature dependences of the expansion coefficients along the a- and c-axis and volume coefficients are obtained, Cea = (1.97349 - 3.84678 x 10(-5)T) x 10(-5), a, = (2.00261 - 3.96007 x 10(-5)T) x 10(-5) and av = (6.01498 - 3.49098 x 10(-4)T) x 10(-5), respectively. No ternary compound is found in the Cu-Ga-N system. Cu and its alloys could have some reaction with GaN under the present experimental condition. (C) 2006 Elsevier B.V. All rights reserved.
