The　influence　of　torsion　deformation　on　textures　of　cold　drawing　pearlitic　steel　wires　was　investigated　by　twisting　the　wires　to　different　number　of　revolutions.　Macro-texture　(over　the　entire　wire　cross　section)　associated　with　torsion　deformation　was　investigated　by　X-ray　diffraction,　while　micro-texture　(near　the　wire　surface)　was　characterized　by　EBSD.　The　results　show　that　the　h110i　macro-texture　increases　at　the　beginning　of　torsion　and　then　decreases　with　increasing　of　torsion　strain,　while　the　h110i　micro-texture　decreases　linearly　with　increasing　of　torsion　strain.　The　relationships　between　the　h110i　fiber　texture　and　the　microhardness　of　the　wires　are　also　discussed.　©　The　Chinese　Society　for　Metals　and　Springer-Verlag　Berlin　Heidelberg　2015.
