摘要
通过系列加热温度、保温时间试验、析出相的检测,对水电站用钢SXQ500/550DZ35奥氏体晶粒的长大进行研究,确定完全奥氏体化的推荐温度为900~950℃,推荐保温时间在20~60 min,目的在于通过细化晶粒钢保证其低温冲击韧性,并为后期热处理工艺的完善提供相关依据。
Through a series of heating temperature,holding time tests and detection of precipitated phases,the austenite grain growth of SXQ500/550DZ35 steel for hydropower station is studied.It is determinted that recommended temperature for complete austenitization is 900-950℃,and the recommended holding time is 20-60 min.The purpose is to ensure its low temperature impact toughness by refining grain steel,and to provide relevant basis for the improvement of later heat treatment process.
