Hydrogen embrittlement (HE) is increasingly becoming a critical issue for using high-strength steels in the automotive and infrastructure industries. To overcome the risk posed by HE of structural components under a hydrogen uptake environment in ...
Hydrogen energy society has required for lower cost BCC metals with high-resistance to hydrogen environmental degradation instead of FCC metals with higher cost. However, BCC metals such as steels have higher degradation susceptibility than FCC me...
Though various experiments of hydrogen in metal have been studied, there is very little understanding of hydrogen trapping states and degradation in aluminum. This is because the hydrogen dissolution enthalpy of aluminum is very high. In the prese...
High-strength steel has been required from the viewpoint of reduction in cost and environmental deterioration in recent years. However the probability of delayed fracture caused by hydrogen increases with steel strength. As universal mechanism of ...
The main role of hydrogen in hydrogen embrittlement has been investigated for fcc and bcc metals. Both fcc and bcc metals show that hydrogen contents of the strained metals with hydrogen are more than those of strained metals without hydrogen. It ...
Hydrogen embrittlement has been analyzed by using thermal desorption spectrometry (TDS). However, it is difficult to separate the states of trapped hydrogen at various lattice defects such as dislocation and vacancy. It is reported that peaks of h...
