【 摘 要 】

Effect of addition of rare earth metals on microstructure and properties of copper alloys after casting, after cold working and after heat treatment was studies in this paper. Methodology consisted of microstructure investigations by optical microscopy and scanning electron microscopy. In addition, distribution of alloying elements and electron backscattered diffraction results (EBSD) were presented. The mechanical properties of a wire after tension test and after hardness measurements were described. Electrical conductivity test was performed using Foerster Sigmatest and Thomson bridge. Analysis of the microstructure and mechanical properties of investigated alloys after casting and after metal working showed possibility to produce materials with preferred set of functional properties.
