摘要：
The present study is concerned with the design of Al2TiO5/Al2O3 system functionally graded material (FGM). The samples with various volume content of Al2TiO5 were prepared by the powder metallurgy method. The basic material properties of the samples were then tested and used as a basis for predicting the material proper-ties of the transient layers in Al2TiO5/Al2O3 FGMs. The thermal stresses produced in the fabrication process were simulated by using a finite element method. On the basis of the comprehensive considerations of the minimum residual thermal stress and distribution state, the optimum compositional distribution in Al2TiO5/Al2O3 FGMs was achieved.
