The　aim　of　this　study　is　to　identify　ways　for　controlling　forming-induced　distortion　of　a　dissimilar　Ti6Al4V/AA1050　laminate　prepared　by　a　novel　non-equal　channel　lateral　co-extrusion　process,　which　is　a　modified　equal-channel　angular　pressing　process　(ECAP)　and　is　characterized　by　stimulant　diffusion　bonding　via　a　decrease　in　the　activation　energy.　First,　a　thermo-mechanical　model　of　non-equal　channel　lateral　co-extrusion　based　on　the　DEFORM-3D　software　was　established　along　with　the　introduction　of　modeling　technology.　Second,　the　forming-induced　distortions　of　the　dissimilar　Ti6Al4V/AA1050　laminate　were　evaluated　in　terms　of　all　designed　extrusion　parameters　such　as　the　stripping　angle,　average　velocity　relative　deviation,　average　temperature　relative　deviation,　and　extrusion　force.　Third,　the　process　optimization　for　the　mitigation　of　co-extrusion　distortions　was　performed　by　employing　the　orthogonal　experimental　design　and　signal-to-noise　ratio　method.　Finally,　the　experimental　validation　of　numerical　model　was　carried　out　by　using　the　optimal　process　configuration.　The　variable　analysis　of　the　results　indicates　that　the　pre-heating　temperature　and　the　ram　speed　have　a　considerable　effect　on　forming-induced　distortion　modes.　The　influences　of　process　parameters　on　the　average　temperature　relative　deviation　are　obviously　greater　than　that　on　the　stripping　angle　and　average　velocity　relative　deviation.　In　addition,　the　impact　of　process　parameters　on　the　extrusion　force　is　similar　to　that　of　the　average　temperature　relative　deviation.　The　experimental　forming-induced　distortion　of　the　co-extruded　laminate　is　in　good　agreement　with　the　simulation　result.　Thus,　this　work　provides　an　alternative　guideline　for　the　manufacture　and　distortion　control　of　dissimilar　bimetal　laminates　prepared　by　co-extrusion.
