“…The systematic change of the stable structure type from C15 to C14 and again to C15 in transition metal Laves phases had already been observed in earlier studies [94,120]. In this context, a special complication arises from the problem of the definition of the valencies for transition metals.…”

“…Up to now, very limited work has been done on the phase equilibria of the Co-Ta-Ti ternary system [7,8]. Kuo [7] claimed that an MgZn 2 -type Laves phase of stoichiometric TaTiCo was observed.…”

“…Kuo [7] claimed that an MgZn 2 -type Laves phase of stoichiometric TaTiCo was observed. To ascertain if the TaTiCo Laves phase reported by Kuo [7] is thermodynamically stable, Ayers and Richards [8] four Ta-Ti-Co alloys (viz. TaTiCo, TaTi 2 Co, TaTiCo 2 and Ta 2 TiCo, in at.%) by arc melting and investigated the structures of the four Ta-Ti-Co alloys in the as cast state and after heat treatment in a vacuum furnace at 1000 • C for 24 h by means of metallography and X-ray diffraction.…”

a b s t r a c tThe phase equilibria of the Co-Ta-Ti system at 950 • C were investigated via a combination of diffusion couples and equilibrated alloys. The samples were examined by means of optical microscopy, X-ray diffraction, scanning electron microscopy, and electron probe microanalysis. The experimental results showed the existence of no ternary compounds at 950 • C. Two continuous series of solid solutions form between ␥-TaCo 2 and TiCo 2 (h), and between ␤-TaCo 2 and TiCo 2 (c), respectively. The 950 • C isothermal section consists of 10 single-phase regions, 15 binary phase regions and 6 ternary phase regions. The following six three-phase equilibria at 950 • C were well determined: (1) (Co) +

“…The assessed results for the Mn-X systems are presented in Fig. 9 compared with the experimental data [50,69,[91][92][93][94][95][96][97][98][99][100][101][102][103][104][105][106]. The Mn-X systems show an excellent agreement except that the assessed data for Mn-Tm is about 8% higher than the experimental data [101].…”
