Figure 1

X-ray diffraction pattern (a) and microstructure (b–g) of as-cast Ti2AlNb-based alloy. (b) Stereoscopic image showing coarse grains; (c) SEM back-scattered electron micrograph showing dark α2-Ti3Al, gray B + O-Ti2AlNb phases; (d) TEM bright field image along with (e–g) the corresponding SAED patterns of points 1 and 2, and crystallographic orientations, where 1 stands for O-Ti2AlNb phase, and 2 denotes B2 phase.
