Tensile Property and Strengthening Mechanism of 2297 Al-Li alloy AITranslate
Abstract AITranslate
The microstructure and tensile property of 2297-T87 Al-Li alloy in the 1/2 thickness layer were investigated by optical microscopy,scanning electron microscopy,transmission electron microscopy and tensile tests.The results show that the tensile property of 2297-T87 Al-Li alloy in different directions in the same thickness layer have obviously anisotropic.The tensile strength law is LT direction >L direction >45° direction >ST direction,the elongation law is L direction >45°direction >LT direction >ST direction.L direction,LT direction and 45° direction are mixed fracture dominated by plastic fracture,while brittle fracture is dominant in ST direction.The main precipitated phases in the crystal are lath T1 phase and acicular θ'phase.The number of T1 phase is significantly higher than θ'phase,which is the main strengthening phase of 2297 alloy.
