| Popis | The spatial orientation of ? lamellae in a metastable ß-Ti matrix of Timetal LCB (Ti–6.8 Mo–4.5 Fe–1.5 Al in wt%) was examined and the orientation of the hexagonal close-packed ? lattice in the ? lamella was determined. For this purpose, a combination of methods of small-angle X-ray scattering, scanning electron microscopy and electron backscatter diffraction was used. The habit planes of ? laths are close to {111}ß, which corresponds to (1320)? in the hexagonal coordinate system of the ? phase. The longest ? lamella direction lies approximately along one of the <110>ß directions which are parallel to the specific habit plane. Taking into account the average lattice parameters of the ß and ? phases in aged conditions in Timetal LCB, it was possible to index all main axes and faces of an ? lath not only in the cubic coordinate system of the parent ß phase but also in the hexagonal system of the ? phase. |
