On the texture and superstructure formation in Ti–TiAl3–Al MIL composites

“…Based on the results obtained, the volume fraction of the superstructure increases as one approaches the interface with Ti and, accordingly, decreases as one approaches the interface with aluminum. A similar result was obtained by Maas et al [25]. Moreover, they observed that the amount of the Ti8Al24 phase decreases with an increase in the annealing temperature.…”

“…Despite many studies devoted to the diffusion growth of titanium trialuminide were published in recent decades, to the best of our knowledge, the formation of a Ti8Al24 superstructure in MIL composites was reported only in the current paper and in the studies of Maas et al [25], and van Loo and Rieck [41]. There can be several explanations for this.…”

“…The study of Maas et al [25] was one of the pioneering works devoted to the diffusion growth of intermetallic layers between Ti and Al plates. They revealed several interesting features of the TiAl3 layer growth, which were rarely discussed in subsequent publications.…”

“…In recent research the intermetallic layer texture was studied by electron backscatter diffraction (EBSD) method [23,[26][27][28][29][30][31]. It is interesting to note, that the formation of [001]-fiber texture near the interface Ti/TiAl3 was observed in studies [25,28,31], but the texture at the interface Al/TiAl3 was either not discussed in these papers, or its absence was reported [28].…”
