Elastic-plastic deformation gradients and electrolytically charged hydrogen
Year: 2025
Type: article
Abstract: Multi-scale atomistic simulations investigated the role of interstitial hydrogen in modulating the room-temperature carbon Snoek response in single-crystal bcc-iron. Complementary local dynamical mechanical analysis (nano-dma) experiments revealed an enhanced/stronger carbon Snoek response in the presence of interstitial hydrogen. This originated from elastic-plastic deformation gradients imposed through electrolytically charged hydrogen. Deformation gradients were conclusively established through ‘direct’ observations from X-ray and electron diffraction. The latter, in particular, provided microscopic evidence of hydrogen content and/or activity; and thereby holds ‘uncharted’ potentials for future research.
