The diffusion bonding procedure. In-between the 2 OO3 and this interface layer, it can be feasible to observe a thin layer ( 1 ) composed of alternated various grey layer, it truly is achievable to observe a thin layer (1 ) composed of alternated distinct grey columnar little grains. On the other hand, it it was not achievable to execute EDS analyses owingits columnar compact grains. Even so, was not feasible to execute EDS analyses owing to to decreased thickness. its decreased thickness.(a)(b)(c)Figure six.

The confirmation of the phases in the Nitrocefin Data Sheet interfaces was carried out by EBSD, which The confirmation from the phases at the interfaces was conducted by EBSD, which alallows Kikuchi Olesoxime Inhibitor patterns of tiny zones to become obtained resulting from the lowered interaction volume. lows Kikuchi patterns of tiny zones to become obtained resulting from the decreased interaction volume. Figure 7 shows EBSD Kikuchi patterns in the joint processed at 1000 C for 60 min. This Figure 7 shows EBSD Kikuchi patterns on the joint processed at 1000 for 60 min. This technique was of paramount significance to confirm the presence in the -TiAl intermetallic phase close towards the Al2 O3 base material.approach was of paramount value to confirm the presence on the -TiAl intermetallic phase close to the Al2O3 base material.Metals 2021, 11,Table 1.
