“…Copper and copper-based alloys have been widely utilized in electrical and electronic industries due to a desirable combination of excellent electrical and thermal conductivities, improved mechanical properties and good corrosion resistance [1][2][3][4][5]. On the other hand, nickel substrates are massively applied in electronic devices [6].…”

a b s t r a c tPhase diagram of the Cu-In-Ni ternary system was investigated using differential thermal analysis (DTA), scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), and X-ray powder diffraction (XRD) methods. Experimentally obtained results were compared with the results of thermodynamic calculation of phase equilibria based on calculation of phase diagram (CALPHAD) method and literature data. Phase transition temperatures of alloys with overall compositions along three selected vertical sections Cu-In 0.5 Ni 0.5 , Cu-In 0.8 Ni 0.2 and x(In) = 0.4 were measured by DTA. Liquidus temperatures were experimentally determined and compared with the results of thermodynamic calculation. Identification of coexisting phases in samples equilibrated at 400°C and 500°C was carried out using SEM-EDS and XRD methods. Obtained results were compared with the calculated isothermal sections of the Cu-In-Ni ternary system at corresponding temperatures. Calculated liquidus projection and invariant equilibria of the Cu-In-Ni ternary system were presented.

“…Such wide applications of copper is due to the reason that copper is tough, ductile and malleable materials and key properties of copper alloys are excellent electrical and heat conductivity, good erosion, corrosion and biofouling resistance, high strength, good machinability, non-magnetic, etc. [6][7][8][9][10][11]. It is important that all used copper is recyclable without any loss of quality.…”

Phase diagram of the Bi-Cu-Ga ternary system has been investigated experimentally with 27 alloys and analytically by using a Calphad method. Thirteen annealed alloys at 200 °C were investigated by using scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), and X-ray powder diffraction (XRD) methods. Temperatures of phase transformation were determined with 14 alloys which are lying along three vertical sections .5 by using differential thermal analysis (DTA). Based on the experimental result and by using Calphad method, ternary phase diagrams were constructed with a new description of liquidus phase. Calculated phase diagram and experimentally obtained results are in good agreement. Liquidus projection and invariant reaction were calculated by using new thermodynamic parameters for liquidus phase.

To the best of our knowledge, the thermodynamic description of ternary Bi-Cu-Ga system has not been investigated up to now. Experimental procedureAll samples with total masses of about 3 g were prepared from high purity Bi, Cu and Ga (99.999 at. %) produced by Alfa Aesar (Germany) in an induction furnace under high-purity argon atmosphere. The average weight loss of the samples during melting was about 1 mass %.After melting, samples for the SEM-EDS and XRD investigation were put into quartz glass

Ternary mixture of Cu, Mg, and Ni with the nominal composition of nanocrystalline Cu 50 Mg 25 Ni 25 (in at.%) was milled for 25 hours. Analysis of an X-ray diffraction pattern (XRD) and transmission electron microscopy (TEM) was used to characterize the chemical phases and microstructure of the final product, which is shown to consist of ternary alloy of Cu-Mg-Ni with FCC structure along with small amounts of FCC MgO and Mg 0.85 Cu 0.15 . The good agreement between the size values obtained by XRD and TEM is attributed to the formation of defect-free grains with no substructure during ball milling. Dynamic recrystallization may be a possible mechanism for the emergence of such small grains (<20 nm). The particle size distribution and morphological changes of Cu-Mg-Ni powders were also analyzed by scanning electron microscopy (SEM). According to the SEM results, the particle size of the powders decreased with increasing milling time. Lattice parameter of the Cu-Mg-Ni ternary FCC alloy formed during mechanical alloying increased with increase in milling time from 3.61 to 3.65 Å after 20 hours milling.
