Isothermal section of the Ho-Cо-Sn system at 770 K

The 1300 8 C isothermal section in the Nb – Sn – C ternary phase diagram

In this paper we map out the 1300 8C isothermal section in the Nb–Sn–C ternary system. The results show that the only ternary compound in the system, Nb SnC, is in equilibrium with Sn, NbC , and Nb Sn, but not with Nb, Nb C or C. The Nb SnC phase is not a 2 x 3 2 2 stoichiometric compound but exists over a range of compositions that range from an Nb:Sn:C ratio of |54:22:24 at.%, when in equilib...

Experimental Investigation of the Mg-Nd-Zn Isothermal Section at 300 °C

The Mg-Nd-Zn isothermal section at 300 °C was established in the full composition range using diffusion couples and equilibrated key alloys. Microstructural characterization was carried out using WDS, XRD, and metallographic methods. The homogeneity ranges of the binary and ternary compounds were determined by WDS analysis. Six ternary compounds were observed in the Mg-Nd-Zn system at 300 °C. T...
