Abstract

With the aid of SEM and DTA, the microstructures at metal side of interface between Ti48Al2Cr2Nb alloy and Y₂O₃, ZrO₂ (Y₂O₃ stabilized), ZrO₂ (MgO stabilized), and Zircon sand were investigated, respectively. The initial reaction temperatures were measured for Ti48Al2Cr2Nb alloy and Y₂O₃, ZrO₂ (Y₂O₃ stabilized), ZrO₂ (MgO stabilized), respectively. The results show that the microstructure is the coarsest with rosettes-like shape after Ti48Al2Cr2Nb alloy reacts with Zircon sand, and even the smallest with granular-like shape after Ti48Al2Cr2Nb alloy reacts with Y₂O₃. The order of the initial reaction temperatures between Ti48Al2Cr2Nb alloy and four oxide ceramic materials is non-reaction at 1500, 1400, 1380, and 820°C, respectively.
