Indentation deformation mechanism of combined-strengthened modified layer in low-alloy steel under the influence of hydrogen
Source abstract
Abstract
The indentation method elucidated the deformation mechanism of the combined-strengthened modified layer in low-alloy steel under hydrogen influence. The deformation mechanisms and hardening degrees varied across different zones. The results indicated that the coordinated deformation of grain boundaries, facilitated by hydrogen atoms and dislocation slip, were the primary causes of hydrogen hardening. Furthermore, a uniform distribution of hydrogen traps and grain refinement could mitigate the effects of hydrogen and local plastic deformation on the alloy steel. This study establishes a relationship between hydrogen embrittlement behavior and microstructure, offering a method for investigating hydrogen embrittlement in gradient structural materials.
