Utilizing five groups of bulk diffusion couples together with electron probe microanalysis technique, the composition-dependent ternary interdiffusion coefficients in fcc Cu–Ni–Sn alloys at 1023K were determined via the Whittle and Green method. The presently obtained interdiffusion coefficients at 1023K as well as our previously measured ones at 1073K were combined with the slightly modified thermodynamic...
Both experimental investigation and thermodynamic modeling were performed for the Mg–Mn–Sr system. Four decisive alloys were selected and prepared using a powder metallurgy method to measure the isothermal section at 500°C via a combination of X-ray diffraction (XRD) and electron probe microanalysis (EPMA). No ternary compound has been observed for this ternary system. Four three-phase regions, (Mg)+(αMn)+Mg...
By employing six groups of bulk diffusion couples together with electron probe microanalysis technique, the composition dependence of ternary interdiffusion coefficients in Co-rich fcc Co–Mo–W alloys at 1373K was determined via the Whittle and Green method. The experimental interdiffusion coefficients were critically assessed to obtain the atomic mobilities of Co, Mo and W in fcc Co–Mo–W alloys by...
Based on the available experimental phase equilibria and thermodynamic data, the Sr–In and Sr–Bi systems have been assessed by means of the CALPHAD technique. The solution phases (Liquid, (αSr), (βSr), (In) and (Bi)) were modeled with the Redlich–Kister polynomial. All the intermetallic compounds (SrIn5, SrIn3, Sr2In5, SrIn2, Sr2In3, SrIn, Sr5In3, Sr3In, SrBi3, Sr11Bi10, αSr5Bi3, βSr5Bi3 and Sr2Bi)...
The Sr–X (X=H, Li, Na, Sc) systems are critically reviewed and modeled by means of the CALPHAD technique. The two-sublattice model is used to describe the solid solution phase in the Sr–H system, and the gas phase is treated as an ideal gas mixture of the species H, H 2 , Sr and Sr 2 . All the intermetallic compounds (αSrH 2 , βSrH 2 , Sr 6 Li 23 and...
