PM-HIP Mechanical Data Archive
This is the mechanical testing data archive from a neutron irradiation campaign of nuclear structural alloys fabricated by powder metallurgy with hot isostatic pressing (PM-HIP). Data in this archive include uniaxial tensile testing data, fractography of selected tensile bars, and nanoindentation. The irradiation campaign was designed to facilitate a direct comparison of PM-HIP to conventional casting or forging. Five common nuclear structural alloys were included in the campaign: 316L stainless steel, SA508 pressure vessel steel, Grade 91 ferritic steel, and Ni-base alloys 625 and 690. Irradiations were carried out in the Advanced Test Reactor (ATR) at Idaho National Laboratory (INL) to target doses of 1 and 3 displacements per atom (dpa) at target temperatures of 300ºC and 400ºC through the DOE Office of Nuclear Energy, Nuclear Science User Facilities (NSUF) project 15-8242.
Steps to reproduce
Uniaxial tensile tests were conducted following ASTM E8 specifications using a 13M Instron load frame. Fractography of selected tensile bars was conducted using a Lyra3 Tescan scanning electron microscope (SEM) to image the fracture surfaces. Nanoindentation was conducted by making 6 x 5 indent arrays using a Hysitron TI-950 TriboIndenter operating in ambient temperature and atmosphere.
