Abstract:T1'phase in Al-2. 6Li-1. 3Cu alloy was studied systematically by selected area electrondiffraction , serial rotution and matrix analysis of electron diffraction pattern. The results showthat the crystalline structure of T1'phase is orthohombic. The lattice parameters are a =0. 2876 nm, b = 0. 86 nm , c = 0. 406 nm , and orientation relationship with the matrix is(010) T1'//(110)α，[001] T1'//[100]α
Key words: AI-Li alloy T1' phase orientation relationship crystalline structure
