Abstract:

X-ray diffraction and transmission electron microscopy were used to study the O-phase formation in the Ti-25.6\% Al-13.9\% Nb-0.3\% Mo-0.3\% Zr alloy upon the B2 -> O phase transformation. The formation of pseudotwins is shown to be possible in the B2 phase in the Ti-Al-Nb alloys. It is found that the O phase upon the B2 -> O phase transformation does not undergo twinning, and all twins observed in the alloy belong to the intermediate metastable B19 phase. The orthorhombic O phase is formed upon ordering inside the B19-phase twins and save their boundaries.
