摘要/Abstract

摘要： 利用扫描电镜(SEM)、X射线衍射仪(XRD)和拉伸试验机等系统研究了0.2C-5Mn-1.5Al-0.5Si中锰TRIP钢经不同预处理及临界退火处理后的微观组织演变和力学性能变化。结果表明,缩短预处理时间,不影响珠光体含量,但是能细化铁素体与马氏体晶粒;730 ℃临界退火5 min时,试验钢组织中皆出现了块状和薄膜状的两种残留奥氏体,而预处理时间更短的试验钢中奥氏体与铁素体晶粒更细;预处理时间短的试验钢抗拉强度和断后伸长率整体高于预处理时间更长的试验钢,并在预处理时间较短的工艺下,退火后获得最佳力学性能:断后伸长率为34%,强塑积为34.34 GPa·%,在拉伸过程中没有屈服延伸现象,具有良好的加工硬化能力。

Abstract: Microstructure evolution and change of mechanical properties of the 0.2C-5Mn-1.5Al-0.5Si medium manganese TRIP steel after different pretreatments and intercritical annealing treatment were systematically studied by means of scanning electron microscope (SEM), X-ray diffractometer (XRD) and tensile testing machine. The results show that with the shortening of pretreatment time, the pearlite content does not change, but the ferrite and martensite grains are refined. When intercritically annealed at 730 ℃ for 5 min, two kinds of retained austenite in the form of block and film appear in the microstructure. The grains of austenite and ferrite in the steel under shorter pretreatment time are finer. It is found that the tensile strength and elongation of the tested steel under shorter pretreatment time are generally higher than those under longer pretreatment time. Under the process with a shorter pretreatment time, the optimal mechanical properties are obtained after annealing, with elongation of 34%, the product of strength and elongation of 34.34 GPa·%, and there is no yield extension phenomenon during the tensile process, with good work hardening ability.
