WebDirect hydrogenation of CO2 (or HCO3–) into chemicals using organic waste biomass as a hydrogen donor is a promising carbon-negative strategy to alleviate the global warming … Web4 Jul 2024 · The GNDs density is much lower than SSDs density in GNT metals, and the contribution of GNDs to work hardening is mainly due to its promoting effect on SSDs rather than its effect on flow stress. ... We hold the opinion that the GNT structure plays a positive role in the improvement of GNT-1 back stress, but the promoting effect of GNDs on SSDs ...
WebResults reveal that GNDs, absent in conven- tional plasticity predictions, play a fundamental role on hydrogen transport ahead of a crack. SGP estimations provide a good agreement with experimental measurements of crack tip deformation and high levels of lattice hydrogen concentration are predicted within microns to the crack tip. Web1 Jan 2011 · Mughrabi's (2006) recent report on the role of GNDs also substantiates our observed experimental results on the density of dislocations. Ideally, all microstructural features including GNDs should of course be integral parts of work-hardening theories. 10 Concluding remarks We reported the evolution of GNDs in the presence of different …
