Abstract:
High strength fastener alloys are typically composed of martensitic microstructures. However, they are susceptible to hydrogen embrittlement particularly as strength increases. This presentation will explore the effect various microstructure and alloy design strategies on hydrogen embrittlement response. The microstructure design strategies include high strength bainitic microstructures, quenched and partitioned microstructures composed of martensite and retained austenite, and vanadium and molybdenum microalloyed quenched and tempered martensitic steels. The role of testing methodology on measured hydrogen embrittlement performance will also be discussed.
