Hydrogen Isotope Effect in Embrittlement and Fatigue Crack Growth of Steel

March 7, 2019

Author(s)

Matthew J. Connolly, Andrew J. Slifka, Robert L. Amaro, Elizabeth S. Drexler, May L. Martin

The corrosive effect of hydrogen on steel is a long-standing problem. Corrosion in the presence of hydrogen is, in part, a consequence of the fast diffusion of hydrogen in ferritic steels. Because of the identical chemical properties but large differences

Enumeration of the Hydrogen-Enhanced Localized Plasticity Mechanism for Hydrogen Embrittlement in Structural Materials

February 15, 2019

Author(s)

May L. Martin, Mohsen Dadfarnia, Akihide Nagao, Shuai Wang, Petros Sofornis

This paper presents a review of recent experimental evidence and simulation results enumerating the development of the hydrogen-enhanced localized plasticity (HELP) mechanism as a viable hydrogen embrittlement mechanism for structural materials. A wide

Acceptance of new batches of 9310 steel for the Charpy Machine Verification Program

January 1, 2001

Author(s)

May Ling Martin, Enrico Lucon

During FY2021, one of the NIST Charpy Contractors returned some 9310 steel blanks (rough-machined, oversized, unnotched specimens) that presented visible black surface defects (similar to gouges, some with raised strips of steel). On a couple of these
