Title: Correlation of Yield Stress and Microhardness in 08Cr16Ni11Mo3 Stainless Steel Irradiated to High Dose in the BN-350 Fast Reactor

Abstract

The relationship between the microhardness and the engineering yield stress in 08Cr16Ni11Mo3 steel after irradiation in the BN-350 reactor has been experimentally derived and agrees with a previously published correlation developed by Toloczko for unirradiated 316 in a variety of cold-work conditions. Even more importantly, when the correlation is derived in the K? format where the correlation involves changes in the two properties, excellent agreement is found with a universal K? correlation developed by Busby and coworkers. Additionally, this report points out that microhardness measurements must take into account that sodium exposure at high temperature alters the metal surface to produce ferrite, and therefore the altered layers should be removed prior to testing.
