title = "Study on Interface Reaction and Phase Composition of Titanium Aluminum Alloys Investment Casting",
abstract = "The aim of this study was to research the reaction layers between Titanium Aluminum and ceramic mould shells prepared by the low-cost binder and phase composition of surface of titanium aluminum alloys in investment casting. The ceramic mould shells were prepared with low cost binder and different refractory materials. Through two types of casting methods (gravity casting and centrifugal casting) the titanium aluminum alloys with rare earth element (Ti-Al-Cr-Nb-RE and Ti-Al-Nb-RE) were cast into the mould shells. The microstructures of investment casting titanium aluminum alloys were observed by Optical Microscope (OM), the distributions of elements of topping investment on the surfaces of titanium aluminum alloys castings was analyzed by Electron Probe Micro-Analysis (EPMA), and the mechanical properties were measured. As a result, the microstructures of two kinds of titanium aluminum alloys were both lamella shape, and lamella was thin. The thickness of reaction and diffusing layer of Ti-47.5Al-2Cr-2Nb-0.3Y alloy was about 80μm, and that of Ti-45Al-5Nb-0.3Y less than 50μm.",
