Open publisher page 0 citations

Abstract

The microstructure and the properties changes of Ti-26 alloy were studied during different deformation and solution and aging treatment by TEM, SEM and X-Ray diffraction analysis. The results indicate that good combination of strength and plasticity can be obtained when the deformation amount is 80% in Ti-26 alloy after 730 ℃× 30 min+500 ℃×10 h AC. The strength has little change and the plasticity improves with the deformation increasing. The microstructure of Ti-26 alloy mainly consists of β phase, short-rod α phase which precipitates dispersedly after the solution-aged.
