New Rapid prototyping technology for the prevention of hydrogen embrittlement of metal strips

摘要

Hydrogen embrittlement is a serious concern for advanced steels. In this research, twin-roll strip vibration castrolling 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.
