dc.description.abstractThe main aim of the research, presented in this paper, is to analyze the structural conditions of the PdNi5 alloy depending on the applied melting atmosphere and casting, as well as monitoring changes in the structural and mechanical properties of PdNi5 alloys after homogenization annealing in order to obtain the required quality castings for further plastic processing -rolling. In one case, the melting and casting of the alloy was done in medium frequency induction furnace in an charcoal atmosphere, while in the second, in a vacuum atmosphere. Hardness and the content of C, H, S were determined, and structural analysis of the cast samples using SEM and EDS analysis, was performed. Furthermore, after homogenization annealing at 800 degrees, 900 degrees and 1000 degrees C, lasting 90 minutes, the hardness was determined and structural analysis with an optical microscope was performed and samples are subjected to plastic processing - rolling, with deformationdegrees epsilon = 92%. Based on the analysis of the results, it was found that the melting and casting in vacuum with optimum heat treatment, could be applied to obtain satisfactory castings and structural characteristics for further plastic processing - rolling. The results presented in this paper may offer further knowledge of the effects various parameters have on the properties of palladium-nickel alloy.en
