“…The same sequence C14-C36-C15 can also be found in pure transition metal systems, e.g. along the section from C14 NbFe 2 to C15 ZrFe 2 [208], and in main group systems such as CaAl 2 -CaLi 2 [209] or CaAl 2 -CaMg 2 [210].…”

“…The phase diagram of this system is shown in Figure 5, after the work of Granovsky et al [14] and the compilation in [15]. The phase of interest is the Laves phase, which exists in its three polymorphic structures, C15, C14, and C36.…”

Abstract:Ternary intermetallic A-B-C systems sometimes have unexpected behaviors. The present paper examines situations in which there is a tendency to simultaneously form the compounds ABx, ACx and BCx with the same crystal structure. This causes irregular shapes of the phase homogeneity domains and, from a structural point of view, a complete reversal of site occupancies for the B atom when crossing the homogeneity domain. This work reviews previous studies done in the systems Fe-Nb-Zr, Hf-Mo-Re, Hf-Re-W, Mo-Re-Zr, Re-W-Zr, Cr-Mn-Si, Cr-Mo-Re, and Mo-Ni-Re, and involving the topologically close-packed Laves, χ and σ phases. These systems have been studied using ternary isothermal section determination, DFT calculations, site occupancy measurement using joint X-ray, and neutron diffraction Rietveld refinement. Conclusions are drawn concerning this phenomenon. The paper also reports new experimental or calculated data on Co-Cr-Re and Fe-Nb-Zr systems.

“…Efforts have also been made to identify the precipitates and the phase transitions causing the formation of these precipitates. [10,11,12] For example, Nikulina et al [13] have shown the presence of Zr 4 Sn and Zr 5 Sn 3 phases in the Zr-1Nb-1Sn-0.4Fe alloy.…”

This article summarizes the evolution of microstructure in binary Zr-1Nb and quaternary Zr-1Nb-1Sn-0.1Fe alloys after (1) b quenching and tempering and (2) cold working and annealing. The morphologies of constituent phases and precipitates, their shape, size, and nature have been studied in detail using transmission electron microscopy (TEM). The b-quenched alloys, in general, exhibited a lath martensitic microstructure. On tempering, the martensitic microstructure underwent considerable changes with respect to the lath dimensions and precipitation behavior, ultimately leading to an equiaxed recrystallized microstructure. Annealing studies of cold-worked binary alloy showed precipitation of the b phase with varying Nb content depending on the heat-treatment temperature and time. In the quaternary alloy, precipitation of the Zr-Nb-Fe type phase along with the b phase took place on annealing the cold-worked samples. High-resolution electron microscopy (HREM) of the recrystallized microstructures was carried out to study the internal structure and the interface structure of the precipitating phases. In the annealing study, mechanical properties of the annealed samples were also determined. Microstructural observations together with mechanical property data concluded that in both alloys, complete recrystallization of the cold-worked microstructures took place on annealing the samples at 853 K for 1 hour.
