利用C-C方法对焊接接头蠕变失效行为的研究

Investigation on the Creep Behavior of Stainless Steel Welded Joints by C-C Method

利用分析焊接接头蠕变破坏的新方法——CryoCracking法,研究了不锈钢0Cr18Ni12Mo2Ti焊接接头的蠕变失效行为,通过对试样断口进行电镜扫描,分析探讨了断口的形貌及温度对接头蠕变行为的影响。

A new testing method called Cryo -Cracking and its application in the study of creep failure for welded joints of stainless steel 0Cr18Ni12Mo2Ti are introduced in this paper. The fracture sections are analyzed under the scanning electron microscope, the morphology of fracture sections and the effect of temperature on the creep behavior of welded joints are also studied.
