The phase diagram of the system CuIn (S xTe 1− x) 2 was obtained from differential thermal analysis (DTA) and X-ray diffraction measurements. DTA measurements were carried out on each sample and the transition temperatures were plotted as a function of alloy composition. A miscibility gap ...
Phase diagram investigation of the Cu–Sn system was carried out on twenty Cu-rich samples by thermal analysis (DTA), metallographic methods (EPMA/SEM-EDX) and crystallographic analysis (powder XRD, high temperature powder XRD). One main issue in this work was to investigate the high temperature...
DTA-DTG, X ray diffraction and metallographic measurements at different temperatures and partial oxygen pressure in the isoplethic cut ``(Bi,Pb)2Sr2CuOx-CaCuO2'', were carried out to analyze the influence of partial constraint oxygen pressure on phase transformations. An isobaric invariant equilib...
In this work, Cu-10.5 at.% Sn is selected to investigate the crystal orientation of primary phase and the occurrence of peritectic reaction during directional solidification under a transverse static magnetic field. According to the Cu-Sn phase diagram, the phase transformation of Cu-10.5 ...
Increasingly, nanoscale phase coexistence and hidden broken symmetry states are being found in the vicinity of metal-insulator transitions (MIT), for example, in high temperature superconductors, heavy fermion and colossal magnetoresistive materials, but their importance and possible role in the MIT and...
a根据Sn-Cu、Ag-Sn、Sn-In二元相图可知Cu6Sn5、Ag3Sn、Ag4Sn、InSn4、In3Sn等相也都是在润湿实验结束后的冷却过程中形成的。 According to Sn-Cu, Ag-Sn, the Sn-In dual phase diagram may know Cu6Sn5, Ag3Sn, Ag4Sn, InSn4, In3Sn and so on also all is ended in after undercooling at...
The isothermal section of the phase diagram of the ternary system La–Ni–Cu has been investigated by X-ray diffraction, differential thermal analysis, optical microscopy and electron microscopy techniques. It consists of 13 single-phase regions, 23 two-phase regions and 11 three-phase regions. ...
This group of rocks has a unique distribution of trace elements on a primitive mantle-normalized diagram (Fig. 8D). Although the Ba, K, and Pb contents are higher relative to the elements on both sides, LILE and LREE in these rocks are generally depleted compared to HFSE and HREE, and...
Figure 5.(a) Cu-In phase diagram [22], by courtesy ofJournal of Phase Equilibria, copyright Springer Nature. (b) Summary of the evolution of the catalyst NPs after the different treatments. In is oxidized by air after deposition. Both In and the oxide are amorphous at this stage. The ...
According to the Cu–Sn phase diagram [31], Cu6Sn5 and Cu3Sn were the two equilibrium phases that formed between the Cu and Sn at the examined soldering temperature. Thus, the submicron-thick IMC layer that nucleated between the Cu6Sn5 and Cu was likely Cu3Sn. However, it was ...
