摘要：
Intermetallic alloys based on an ordered orthorhombic phase Ti2AlNb, hereafter referred to as the Ti2AlNb-based alloys, are continually developing as attractive materials for aerospace applications due to their desirable properties like a unique combination of strength and ductility, good creep resistance, and low densities. This review article is thus aimed at summarizing recent advances on the microstructural evolution and mechanical properties of the Ti2AlNb-based alloys. Particular attention is paid to their crystal structure, phase transformations, microstructure and hot forming processing.
