摘要	An ideal method has been established for calculating the precipitation Of alpha(2) ordered phase in near-a titanium alloys based on the theory on the critical electron concentration for the precipitation of alpha(2) ordered phase in near-alpha titanium alloys. With complete precipitation of alpha(2) phase in near-a titanium alloys, the alloys can be considered to be composed of two parts: (1) the alpha(2) ordered phase with the stoichiometric atomic ratio of Ti3X; (2) the disorder solid solution with the critical composition in which the alpha(2) ordered phase is just unable to precipitate. By using this method, the volume fractions of alpha(2) ordered phase precipitated in Ti-Al, Ti-Sn, Ti-Al-Sn-Zr alloys with various Al, Sn and/or Zr contents have been calculated. The influences of Al and Sn on the precipitation of alpha(2) ordered phase are discussed. The calculating results show substantial agreement with the experimental ones.
