摘 要：The Orthorhombic Ti2AlNb-based alloys (O alloys) are potential high temperature materials for applications in aircraft engines for their high specific strength. In this paper, with the purpose of enhancing the mechanical properties, W is added to O alloys as the quarternary alloying element. The effects of W additive on the high temperature tensile properties and creep resistance are investigated. The effects of boron doping on these properties are also studied.
