摘要：

In this study, annealing treatment treatments with different temperatures (800 degrees C, 900 degrees C, 950 degrees C, and 965 degrees C) were first conducted on rolled near-alpha Ti-6Al-3Nb-2Zr-1Mo alloy. The microstructure evolution behaviour and mechanical properties of this alloy were studied. Evaluation of the microstructures heat treated for 1 h indicated that the primary alpha particles were coarsened with increasing heat treatment temperature. The relationship between yield strength and the alpha grain size, defined with the high boundary tolerance angle (> 10 degrees), follows the Hall-Petch approach. The increasing ductility indicates that the strain hardening capacity decreases as a result of the coarsening behaviour of primary a and kinked coarsening of as (the secondary a phase) lamellae.
