Sheet-Shape Specimen Creep Behavior and Microstructure Analysis of Ni-Based Alloy C276 at High Temperature

Abstract:

Ni-based Alloy C276 is a candidate material for the fuel cladding of super critical watered reactor (SCWR). In this paper, Alloy C276 was cut to a slice (thickness near to the fuel cladding) to investigate its creep character at 600-750oC with stress 130-240MPa. Scanning electron microscope (SEM) was used to analysis the microstructure of sheet-shape specimens (SS) and bar-shape specimens (BS). The result shows that SS have larger elongation and shorter lifetime than BS. By analyzing SEM images, we can infer that the different exfoliations made the different creep behavior of SS and BS.
