Solid-State Processing Route, Mechanical Behaviour, and Oxidation Resistance of TiAl Alloys

Figure 11

Size of the -grains mapped by EBSD between powder particles (densification at 1421 K). Grains are coloured in the function of their size (see colour scale) defined as the diameter of the circle of the same area. Small grains (in blue) are concentrated in the neck regions. The gains are coloured in olive green. The arrow indicates a concave interface for the particle at the middle right, indicating a strong plastic deformation of this particle, as adopted from [96].
