Hydrogen, the key element for solving the major environmental issues, exhibits rapid
diffusion and localization in lattice defects of metals, which leads to embrittlement. However …

The microscopic hydrogen diffusion in UNS S32750 super duplex stainless steel was
analyzed using a polyaniline-nickel-based hydrogen video imaging system. The hydrogen …

To understand hydrogen uptake into an Fe sheet due to corrosion, a hydrogenochromic
sensor consisting of polyaniline and Ni layers was employed for the real-time visualization of …

The distribution of hydrogen entering an Fe sheet under a droplet of NaCl solution was
successfully visualized using a hydrogenochromic sensor consisting of a polyaniline layer …

A quantitative relationship between optical and electrical properties of crystalline WO 3 films
during Li+ insertion has been established in this work. Detailly, the exponential relationship …

Local hydrogen entry under a NaCl droplet on Fe sheets was analysed by employing a
hydrogenochromic sensor and electrochemical hydrogen permeation tests. Large …

A hydrogen visualization method with high responsivity and chemical stability under
atmospheric corrosion is necessary to inhibit hydrogen embrittlement, which can occur with …

This study investigates the effects of hydrogen embrittlement (HE) on Inconel 718 parts
produced using Electron Beam Melting (EBM) with a spot melting scanning strategy …

Hydrogen diffusion in polycrystalline metals is known to depend on microstructure. The
hydrogen-microstructure interactions have been extensively studied last decades, but the …

抄録 Hydrogen embrittlement is caused by a small amount of hydrogen in steels used under
applied stress, which is a critical issue in the current era when there are growing needs to …
