Microstructure and mechanical properties of TRIP steel by TSCR process
-
摘要: 在實驗室條件下模擬薄板坯連鑄連軋工藝試制了C-Si-Mn系TRIP鋼.拉伸實驗表明,實驗鋼的抗拉強度為610MPa,屈服強度為430MPa,屈強比為0.70,總延伸率為28.4%.組織觀察發現,試樣組織為鐵素體+貝氏體+殘余奧氏體的三相組織,實驗鋼中殘余奧氏體的平均含量為5.8%.Abstract: C-Si-Mn TRIP steel was prepared by TSCR process in laboratory simulation. The results of tensile experiment indicated that the mechanical properties were the tensile strength of 610 MPa, the yield strength of 430 MPa, the elongation of 28.4%, and the ratio of yield strength to tensile strength of 0.70. The micmstructure was comprised of ferrite, bainite and retained austenite. The result of quantitative colour metallography showed the retained austenite fraction around 5.8%.
