Tensile Deformation of Alloy 617 at Different Temperatures

Document Type

Conference Proceeding


Austenitic Alloy 617 has been identified as a candidate structural material in hydrogen generation using nuclear heat. A temperature of 950°C has been recommended to achieve the maximum efficiency in hydrogen generation involving numerous chemical reactions. The tensile properties of this alloy have been determined at temperatures ranging from ambient to 1000°C. Simultaneously, the fracture toughness of this alloy is being evaluated using fracture-mechanics-based compact tension specimen. This paper presents the results of tensile testing of this alloy as a function of temperature. The results of fractographic evaluations using scanning electron microscopy are also included.
