Correlation of microstructure and hydrogen delayed fracture for 1GPa steels

摘要：

Automobile industry tries to reduce the weight of automobile using high-strength steels. However, the high-strength steels are highly susceptible to delayed-fracture caused by hydrogen embrittlement. With increasing the strength, hydrogen embrittlement is more sensitive to diffusible hydrogen. The mechanism of delayed-fracture and the relationship with the microstructure and alloying elements are still ambiguous. This study analyzed the effect of the size and the spheroidization rate for the carbides on hydrogen-induced delayed fracture for 1GPa TS steel.
