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...

The α -phase was found to be unstable in air, and further experiments should be performed in a good vacuum. The phase diagram of Cu 2 x Se was redetermined by the X-ray parametric method and the possible reasons why the phase diagrams reported by several authors do not coincide with ...

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. ...
2.??Binary phase diagram of Cu?Fe alloy 下载:?全尺寸图片?幻灯片目前有关Cu?Fe合金快速凝固的研究工作主要集中在细化凝固组织及液相分离机制研究上。Guo等[25]采用快速凝固与真空熔融相结合的方法制备了Cu?Fe?C合金,研究了不同冷却速率下合金的组织演变,发现当冷却速率在0.515×103?K/s~0.773×104?K/s时...
The superconducting oxide YBaCuOis found in two structures: a tetragonal structure (T) that is stoichiometric when δ=0, and an orthorhombic (O) structure stoichiometric when δ=1. Assuming that only these phases appear in the phase diagram of the oxide as temperature (t) and δ are varied,...
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...
