摘要/Abstract

摘要： 通过OM、SEM、TEM等手段,研究了40Si2Ni2CrMoV钢不同温度淬火(840、860、880、900 ℃)和300 ℃回火后的显微组织和力学性能,并利用相分析法对钢中的析出相进行了定性及定量表征。结果表明,在800~900 ℃淬火时,随着淬火温度的升高,试验钢的组织为板条马氏体,并呈现先细化后粗化的趋势,在880 ℃时组织最细,且均匀性较好;析出相弥散分布于马氏体基体中,随着淬火温度的升高,析出相逐渐回溶。结合力学性能研究,认为880 ℃是该试验钢较合适的淬火温度。

Abstract: Microstructure and mechanical properties of 40Si2Ni2CrMoV steel quenched at different temperatures (840, 860, 880, 900 ℃) and tempered at 300 ℃were studied by means of OM, SEM and TEM, and the precipitates in the steel were qualitatively and quantitatively characterized by phase analysis method. The results show that when quenched at 800-900 ℃, the microstructure of the tested steel is lath martensite and shows a trend of first refining and then coarsening with the increase of quenching temperature. When the quenching temperature is 880 ℃, the steel has the finest and most uniform microstructure, and the precipitates are dispersed in the martensite matrix. As the quenching temperature increases, the precipitates gradually dissolve into the matrix. Combining with the mechanical properties, it is considered that 880 ℃ is a suitable quenching temperature for the tested steel.
