摘要
研究了淬火配分处理对18CrNiMo7-6材料组织和性能的影响.试验结果表明,淬火配分工艺可以有效提高组织中奥氏体的含量,在保证材料抗拉性能基础上有效提升材料的冲击性能和延伸率.配分初期,抗拉强度较高,延伸率相对较低.配分过程中,抗拉强度随着时间的增长而下降,延伸率随之上升.配分完成后,抗拉强度和延伸率先下降,然后随着配分时间的继续增长而再次上升.
Abstract
This experiment systematically studied the effects of quenching and partitioning(Q&P)treatment on the microstructure and properties of 18CrNiMo7-6 steel.The results indicate that the Q&P process can effectively increase the austenite content in the microstructure,thereby enhancing the impact toughness and elongation of the material while maintaining its tensile strength.Initially,during the partitioning stage,the tensile strength is relatively high,and the elongation is comparatively low.As partitioning progresses,the tensile strength decreases with time,while the elongation increases.After the partitioning is completed,both the tensile strength and elongation initially decrease,then increase again with further partitioning time.
