文摘

Hydrogen embrittlement was studied on tempered experimental microalloyed steel. UTS, YS and %E tend to decrease as the hydrogen charging time increases. Precipitation kinetics affect the mechanical properties of tempered steels. 400 °C–10 and 300 min condition were less susceptible to hydrogen embrittlement. Hydrogen permeability parameters change due to the evolution of hydrogen traps.
