Abstract Scope |
The hydrogen embrittlement (HE) behavior of hot-stamped ultra-high strength boron steel B1500HS was studied. A series of tensile tests and microstructure observations for B1500HS samples after electrochemical hydrogen charging were performed and analyzed. Based on the experimental results, some interesting phenomena were studied. Firstly, the relationship between the mechanical properties of hot stamped B1500HS and the hydrogen concentration and charging time were presented; Secondly, both reversible HE and irreversible HE were revealed and the conditions leading to them were discussed; Thirdly, the effects of tensile rate on B1500HS after hydrogen charging were also studied. Besides, the mechanism of the above phenomena were further involved in this work. |
