摘要: 研究了第三代高強度高塑性TRIP鋼的退火工藝對性能的影響和組織演變規律.熱軋后形成的原始馬氏體與臨界退火時形成的殘余奧氏體使TRIP鋼具有良好的強度和塑性.結果表明:實驗用鋼可獲得1000MPa以上的抗拉強度和30%以上的斷后延伸率,且強塑積>30 Gpa·%;退火溫度和保溫時間對鋼的力學性能具有顯著影響,熱軋TRIP鋼臨界退火溫度為630℃,保溫時間18 h時,實驗用鋼能獲得最佳的綜合力學性能.

Abstract: The effects of annealing processing on the mechanical properties and microstructure evolution of high strength and high ductility TRIP steels were investigated.The hot-rolled-and-annealed TRIP steel has remarkable strength and ductility due to the prior martensitic microstructure obtained in the as-hot-rolled condition and the retained austenite formed during intercritical annealing.The results show that the test steels have a tensile strength of over 1 000 MPa and an elongation of over 30%,and the product of ultimate tensile strength and total elongation exceeds 30 GPa·%.The mechanical properties are significantly influenced by intercritical annealing temperature and soaking time.When the TRIP steel is treated at an intercritical annealing temperature of 630℃ for 18h,the best mechanical properties are obtained.
