“…The phase diagram of the Ti-Co system shows the existence of five intermetallic compounds at 600 • C, i.e. TiCo 3 , TiCo 2 (h) (hexagonal MgNi 2 -type), TiCo 2 (c) (cubic MgCu 2 -type), TiCo and Ti 2 Co, and this has been confirmed in our previous work on the Dy-Co-Ti system [7]. Ray [8] firstly reported ten intermetallic compounds in the Nd-Co system, namely Nd 2 Co 17 , NdCo 5 , Nd 5 Co 19 , Nd 2 Co 7 , NdCo 3 , NdCo 2 , Nd 2 Co 3 , Nd 2 Co 1.7 , Nd ∼7 Co ∼3 and Nd 3 Co. Wu et al [9] reinvestigated the Nd-Co system in the range from 50 to 100 at.% Co, confirmed the existence of seven compounds in this region, and reported their structural data.…”

“…Results of phase identification and composition determination by XRD and SEM/EDS have indicated that alloy Nd13Ti7.2Co79.8 contains three phases NdTi x Co 12−x (the background phase), Nd 2 Co 17 (the grey phase) and Nd 2 Co 7 (the white phase). To determine the solubility range of NdTi x Co 12−x , we prepared alloy samples along the iso-concentration line of 7.7 at.% Nd with the concentration of Ti varying from 7 to 16 at.% based on the reported homogeneity range of phase RTi x Co 12−x for R = Sm [19], Dy [7] and Er [20]. And the homogeneity range of the compound NdTi x Co 12−x was found to be 1.43 ≤ x ≤ 1.82, i.e.…”

“…Dy 4 Co 3 phase cannot be found in its XRD pattern in our work as well, which is in good agreement with the result reported Ref. [11,12,21]. In Ref.…”

“…So, it is essential to have a detailed knowledge of the phase diagrams of RE-Co-M systems. The phase diagrams of Er-Co-V [9], Gd-Co-V [10], Dy-Co-Ti [11] and Dy-Co-V [12] ternary systems have been reported in the literatures. So far, no phase diagram of the Dy-Co-Cr ternary system is found.…”

“…To further understand the relations between formation of the compounds and their properties, the investigation of the phase diagram of the relevant systems is useful. The phase diagrams of Er-Co-V [8], Gd-Co-V [9], Dy-Co-Ti [10], and Dy-Co-V [11], etc. ternary systems have been reported in the literature.…”
