The　purpose　of　this　investigation　is　to　study　the　effect　of　roll　bending　deformation　on　the　microstructure　and　texture　in　an　Al-Li　alloy　with　different　extrusion　aspect　ratios.　The　results　indicated　that　the　substructure　of　most　extruded　fiber　grains　is　not　completely　eliminated　on　the　ND-ED　section　at　position　B　with　a　low　extrusion　aspect　ratio.　However,　the　texture　type　of　the　ND-TD　section　changes　from　a　single　texture　to　an　adjacent　texture　after　roll-bending　deformation,　and　the　texture　intensity　decreases　from　8.3　to　6.1.　With　the　increase　of　the　extrusion　aspect　ratio,　the　effect　of　roll-bending　deformation　on　the　microstructure　began　to　be　obvious,　especially　at　position　C.　A　large　number　of　elongated　recrystallized　grains　along　the　ED　direction　were　transformed　into　approximately　equiaxed　grains　on　ND-ED　section　after　the　roll-bending　deformation.　There　were　also　a　small　number　of　approximately　equiaxed　cell　structures.　The　relative　frequency　of　the　low-angle　grain　boundary　rose　slightly　from　42.1%　to　46.7%.　The　single　texture　moved　to　the　adjacent　texture,　and　the　texture　strength　increased　from　4.8　to　6.3.　©　Published　under　licence　by　IOP　Publishing　Ltd.
