摘要
对16MnR钢热轧板进行了不同的热处理。用系列冲击试验(能量)法,结合冲击断口形貌变化确定了脆性转变温度。光镜(OM)和扫描电镜(SEM)显微组织观察表明,脆性转变温度与热处理及其引起的组织变化密切相关;并且脆性转变温度按下列热处理态顺序降低:热轧态、正火、淬火后高温回火。
The different heat treatment processes were done for the 16MnR steel. Based on fracture analysis of OM and SEM, the ductile-brittle transition temperature was defined by series of impact tests. The observation results indicate that the ductile-brittle transition temperature is closely correlative with the microstructure change caused by heat treatment. The ductile-brittle transition temperature is reduced from hot rolling status, normalizing status to the status of drawing temper after quenching.
