Mechanical Properties and Fracture Characteristics of Welded Joint in GH536 Ni-based Superalloy

Microhardness, tensile properties and fracture toughness of based metal and different zones in welded joint for GH536 obtained by gas tungsten arc welding (GTAW) were studied. The results show that hardness in HAZ is equal to BM, however, hardness becomes higher from fusion line to weld center for f...
