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 effects of pure titanium have been investigated in order to clarify a main factor causing the hydrogen embrittlement. Though a lot of studies reported that the main factor of hydrogen embrittlement of pure titanium was hydride, there is n...
To improve the susceptibility of hydrogen embrittlement, it is important to identify hydrogen trapping site, binding energies, and occupation ratios at various lattice defects in metals. Thermal desorption spectrometer heated from lower temperatur...
High strength steel with lower susceptibility of delayed fracture has been required to be developed, while, generally, steel above 1200 MPa of tensile strength increases the susceptibility. In the present study, the susceptibility of tempered mart...
