EFECTS OF CHEMICAL COMPOSITION ON THE MICROSTRUCTURE AND PROPERTIES OF THE CU-Ge-Sb ALLOYS

Abstract

In the current study a ternary Cu-Ge-Sb system has been experimentally assessed. Chemical and
phase compositions of the alloy samples from three vertical sections Cu-GeSb, Ge-CuSb and Sb-
CuGe were studied using scanning electron microscopy (SEM) and energy dispersive spectroscopy
(EDS) and confirmed by X-ray diffraction analysis (XRD). Hardness of the alloys was measured by
Brinell method while hardness of phases was measured using micro Vickers method. Electrical
conductivity of the studied alloys was measured using eddy current instrument. Based on
experimentally determined values iso-lines of hardness and electrical conductivity for the whole
ternary system were calculated using assumed mathematical models.
