【摘要】 该文在对12Cr1MoV钢母材和焊接接头的疲劳寿命、蠕变寿命和蠕变 疲劳交互作用行为试验研究工作的基础上,重点对12Cr1MoV钢在蠕变 疲劳交互作用下的试验数据进行了整理、分析,在国内首次得出了可供工程应用的12Cr1MoV钢的蠕变 疲劳交互作用寿命评定曲线,并与ASME规范的相关曲线作了比较,对一实例做了寿命评定的验证。更多还原

【Abstract】 The paper presents the systemized and analyzed test results of 12Cr1MoV steel, as well as its weldings, under creepfatigue interacting conditions. This is the first time in this country that technically applicable creepfatigue interaction life evaluation curves have been elaborated. The curves are compared with corresponding ones in the ASME code. A prectical life evaluation example is presented as well.更多还原
