| Abstract | The precipitation Of alpha(2) ordered phase in different aging conditions after solution treatment in beta, high alpha + beta, or alpha phase field in TiAl-Sn-Zr-Mo-Si-Nd (1#) and Ti-Al-Sn-Zr-Mo-Si-Nd-Nb (2#) near-alpha titanium alloys was investigated. The solution-treated microstructures consisted of either a single transformed beta phase (beta(1)), a duplex mixture of the primary alpha phase (alpha(p)) and transformed beta phase (beta(1)), or a single primary alpha phase (alpha(1)). The precipitation characteristics Of alpha(2) phase was determined as a function of aging temperature. When the aging temperature was high enough, the precipitation Of alpha(2) phase occurred predominately at the boundaries and the dislocations, instead of being uniform throughout the beta(t), matrix. The precipitation Of alpha(2) phase in alpha(p), however, was relatively uniform. No apparent difference in the size Of alpha(2) particles was observed. When the aging temperature decreased, the precipitation Of alpha(2) phase became relatively uniform in beta(t), but the preferred precipitation and growth Of alpha(2) phase at boundaries and dislocations was still obvious. When the temperature was sufficiently low, the precipitation Of alpha(2) phase was homogeneous at the boundaries and dislocations as well as throughout the primary alpha phase and transformed beta phase matrix.
