The article presents an experimental study of a phase diagram of a ternary Bi-Ni-Pb system using differential thermal analysis (DTA), scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), and X-ray powder diffraction (XRD) analysis. The investigated ternary alloys were selected from three vertical sections (x(Bi)=0.75, x(Ni)=0.1 and x(Pb)=0.9) and two isothermal sections at 100 and at 300°C. The obtained experimental results were compared with the thermodynamically extrapolated phase diagram of the Bi-Ni-Pb ternary system based on the thermodynamic parameters for the constitutive binary systems available in literature. Reasonably close agreement between the experimental data and the calculated phase diagram was obtained. U ovom radu je predstavljeno eksperimentalno ispitivanje faznog dijagrama Bi-Ni-Pb ternarnog sistema uz pomoć diferencijalne termijske analize (DTA), skenirajućeg elektronskog mikroskopa (SEM) sa energijsko disperzivno spektrometrijom (EDS) i rentgenskom difrakcijom praha (XRD). Ispitivane ternarne legure su izabrane iz tri vertikalna preseka (x(Bi)=0.75, x(Ni)=0.1 i x(Pb)=0.9), i dva izotermalna preseka na 100 i 300°C. Rezultati eksperimenta su upoređeni sa termodinamički ekstrapolisanim faznim dijagramom Bi-Ni-Pb ternarnog sistema na osnovu termodinamičkih parametara sastavnih binarnih sistema koji su dostupni u literaturi. Utvrđeno je dobro slaganje između eksperimentalnih rezultata i proračunatog faznog dijagrama. |
