Abstract

Graphical abstract: Highlights: Self-developed vibration cast-rolling technology to solve rapid prototyping and hydrogen embrittlement. Cross-scale research of the mechanism was carried out by finite element and ab initio calculation. Grain refinement leads to the decrease of diffusible hydrogen content in strips of vibration cast-rolling. Dispersed second-phase carbides act as effective hydrogen traps in strips of vibration cast-rolling. Abstract: Hydrogen embrittlement is a serious concern for advanced steels. In this research, twin-roll strip vibration cast-rolling was developed independently as a novel method for steel strip industrial production that inhibits hydrogen embrittlement. It reduces the hydrogen embrittlement sensitivity by optimizing the microstructure of strip steel products during the manufacturing process. Control experiments and cross-scale simulations were performed to reveal the phenomena and mechanisms that inhibit hydrogen embrittlement. The results show that the twin-roll strip vibration cast-rolling process can effectively reduce the hydrogen embrittlement sensitivity of steel strips.
