摘要：

The phase transformations of Ti-5Al-2Sn-4Zr-4Mo-2Cr-1Fe (beta-CEZ) have been studied during continuous cooling after beta-solution treatment. For this purpose, electrical resistivity measurements and metallographical examinations have been carried out, and the continuous cooling transformation (CCT) diagram of beta-CEZ alloy has been plotted. The different kinds of beta-phase decomposition schemes in beta-CEZ alloy during continuous cooling have been investigated in detail. Two main morphological features of the alpha/beta structure are involved, depending on the cooling rate: the basketweave and the colony structures are observed for high and low cooling rates, respectively. For the intermediate cooling rates, the two morphologies coexist. Finally, a generalized scheme of the beta --> beta + alpha transformation sequences during continuous cooling is presented.
