Abstract:
      In this paper, the effects of varied solution time on the microstructures and tensile properties in α+β phase field of Ti-5553 alloy were studied. The volume fraction and feret ratio distribution of primary α (αp) with varied solution time was emphatically analyzed. The microstructures of Ti-5553 alloy were observed by scanning electron microscopy. The orientation evolution of grain boundary primary α and intragranular α phase during solution was characterized by EBSD technique. The tensile properties were tested by the electronic universal testing machine. The results showed that the volume fraction of αp decreases with the extension of solution time, meanwhile, the equiaxation and coarsening of αp would decrease the resistance to dislocation movement, which resulted in the decrease of strength and the increase of plasticity. The grain boundary αp was truncated in the form of "hot trench " during solution process, however the truncated grain boundary αp remained the same orientation.
