Abstract

The results of an experimental investigation of structural, mechanical and electrical characteristics of the alloys in Au-Ga system are presented in this paper. Selected alloys AuxGay (x = 0.1 — 0.3) were examined using light microscopy and SEM-EDX analysis as well as hardness, microhardness and electroconductivity measurements.

Kurzfassung

Die Ergebnisse einer experimentellen Untersuchung der strukturellen, mechanischen und elektrischen Eigenschaften werden im vorliegenden Beitrag vorgestellt. Hierzu wurden Gold-Gallium-Legierungen AuxGay (x = 0,1 — 0,3) ausgewählt und mittels Lichtmikroskopie und REM-EDX-Analyse untersucht. Außerdem wurden die Härte, die Mikrohärte und die elektrische Leitfähigkeit gemessen.
