摘要：

The grain size of Ti Al alloy castings prepared by traditional casting process is coarse, thus showing poor mechanical properties. In this study, a new type of high performance Ti-46Al alloy tube prepared by vacuum centrifugalcastingtechnologywasintroduced.Thisresearchcomprehensivelyexaminedtheinfluenceof pouringtimeonthemicrostructureandmechanicalperformanceofthecastings,employingbothexperimental approachesandPro Castsimulationmethodologies.Thefindingsindicatethatprolongingthepouringtime facilitates a microstructural evolution from coarse columnar grains to refined equiaxed grains. Under the condition of pouring temperature of 1,600°C, rotation speed of 800 r·min-1 and pouring time of 6 s, the tensile strength of Ti-46Al alloy at room temperature reaches 650 MPa, and the tensile strength at 800°C reaches 705 MPa, which is significantly higher than that of traditional as-cast Ti-Al alloy.
