AbstractTransmission electron microscopy (TEM) and atom probe tomography (APT) techniques were used to investigate the nano-scale ordered alpha(2) (Ti3Al) precipitates in Ti-Al binary alloys. Ti-6Al and Ti-8Al binary alloys were solution treated and aged to obtain Widmanstatten microstructure and promote alpha(2) precipitates. The TEM results displayed strong short-range ordering of alpha(2) precipitates in Ti-8Al alloy, while no evidence of the superlattice reflections of alpha(2) in Ti-6Al alloy. The results acquired from APT showed the alpha(2) clusters and atoms distribution at the interface between the matrix and alpha(2) precipitates. The size and morphology of alpha(2) particles in Ti-8Al alloy, respectively, obtained by TEM and APT are closely consistent. Meanwhile, the APT results displayed tiny size clusters in Ti-6Al alloy, which supposed to give evidence of the initial ordering process of alpha(2) precipitates in the absence of correlative results from TEM.
