摘要:Intermetallic alloys based on an ordered orthorhombic Ti2 AlNb phase are considered as promising materials for aerospace ap-plications.The mechanical properties of the Ti2 AlNb-based intermetallic alloy with three phases of O,B2 and a2 ,are sensitive with the phases and microstructure.In the present work,phase transformation of Ti2 AlNb-based alloy during solution treatment at elevated tem-peratures was investigated by using optical microstructure (OM),scanning electron microscope (SEM),and transmission electron mi-croscope (TEM).The results indicated that the transformation from O to B2 phase occurred and the α2 phase gradually vanishes with increasing the solution treatment temperature.The solution treatment temperature determine the amounts of O,B2 and α2 phase and their final microstructural morphologies,and also determine the properties of the material.
