The authors would like to apologize for any inconvenience regarding misleading errors and inconsistencies in some of the units and one number, and wish to make the following corrections to this paper [1]:
Page 11: unit should be GPa in “…up to 200 GPa [71]…” (not MPa).
Page 12: unit should be GPa in “…lying around 146 GPa…” (not MPa).
Figure 9: units should be GPa for K0 in all four occurrences (not MPa).
Table 1: correct value for K0 for α2 to be “126” (not 116).
Page 16: unit should be GPa in “With values around 146 GPa…” (not MPa).
Figure 9.
Atomic volumetric compression behavior of the investigated composition Ti-45Al-7.5Nb-0.25C with Birch–Murnaghan fits (experimental dots with continuous lines), as compared to α2-single-phase compression, and α- and ω-titanium, reported by Dubrovinskaia [59] and Errandonea [48], respectively.

Table 1.
Compilation of experimental lattice parameters a0 and c0 under ambient conditions, as well as the derived quantities; their axis ratios and volume per atom VA, compression parameters K0, K0’ (first three rows) and data from the literature. The α-phase lattice is given in α2 cell notation, and therefore, 2c/a is noted. The first VA column is computed from a0 and c0, while the second results are from the fit of pressure data to Equation (6). The original data of Yeoh’s publication [31] has been re-visited to extract the listed values at 300 K. Literature values are reported from their experimental findings, in addition to Ghosh’s first-principles study [61]. Further listed references are Dubrovinskaia [59], Errandonea [48], Asta [60], Zhang [55], JCPDS [56], and Menon [78]. a, c in (Å); V in (Å3); K0 in (GPa).
