Purification　preparation　of　high　carbon　copper-bearing　twining　induced　plasticity　(TWIP)　steel　plays　an　important　role　in　fully　exerting　its　outstanding　performance.　To　improve　the　purity　of　high　carbon　copper-bearing　TWIP　steel,　the　types　and　sources　of　inclusions　and　the　varing　trends　with　different　production　processes　were　discussed　by　analyzing　the　non-metallic　inclusions　in　ingot　and　hot-rolled　sheet,　which　was　the　product　of　this　TWIP　steel　vacuum　induction　melting　and　solution　treatment,　with　optical　microscopy,　scanning　electron　microscopy　and　energy　dispersive　spectroscopy.　The　result　indicated　TWIP　steel　mainly　contained　the　inclusions　of　iron　and　manganese　oxides,　silicates,　sulfides　and　nitrides.　Within　the　temperature　range　of　the　application　and　heat　processing　of　the　TWIP　steel,　sulfides　expressed　excellent　plasticity　while　nitrides　were　hard　and　brittle　inclusions.　The　deformation　characteristics　of　the　inclusions　of　silicates　and　iron　and　manganese　oxides　were　greatly　influence　by　its　component　and　temperature　change.
