Influence of welding on low cycle fatigue properties of Co-based superalloy FSX-414

Co-based superalloys such as FSX-414 have been recently used in gas turbine first stage nozzles. During service, nozzles are exposed to low cycle fatigue, which can lead to cracking of these components. The cracks on these nozzles are usually welded with tungsten arc welding (TIG) using Co-based fil...
