    摘要: The present invention provides a TWIP steel sheet that has an austenite matrix structure and includes 15-25 wt % of manganese. The TWIP steel sheet has a recrystallization texture in which brass orientation is suppressed and {3 5 2} is developed as its main orientation during heat treatment subsequent to cold rolling, and has an average plastic strain ratio of 1.2 or more, preferably 1.5 or more. Since this TWIP steel sheet has high workability and strength, complicated vehicle body components can be easily manufactured through a press molding process without cracking or rupturing.

    摘要: Disclosed herein is an ultra high strength TWIP steel sheet having an austenite matrix texture, comprising 0.15˜0.30 wt % of carbon, 0.01˜0.03 wt % of silicon, 15˜25 wt % of manganese, 1.2˜3.0 wt % of aluminum, 0.020 wt % or less of phosphorus, 0.001˜0.002 wt % of sulfur, and residual iron and other inevitable impurities, wherein the TWIP steel sheet is cold-rolled at a reduction ratio of 35˜40% per pass under a condition of 180˜220 Mpa in front and rear tension, and thus has an average plastic strain ratio of 1.2 or more. The ultra high strength TWIP steel sheet has an improved average plastic strain ratio and excellent formability because it has a developed Goss orientation.
