Why is it important?
Particular emphasis is given to the proposal of the novel and unified HELP + HEDE model based on the specific microstructural mapping of the dominant hydrogen embrittlement (HE) mechanisms with implications on the fracture process and resulting #hydrogen-assisted fracture modes.
It is of utmost importance to achieve a unified model for HE based on the synergy between localized plasticity and decohesion, HELP + HEDE model, proposed in 2014/2015 by Djukic et al. and Djukic et al. in 2016 in steels, iron, and other metallic materials.
Recently (2015-2022), the validity of our HELP?+?HEDE model for hydrogen embrittlement was fully confirmed by experiments and models in numerous metallic materials, including different types of steel, iron, nickel, Ni-based alloys, and Al alloys. Our original HELP + HEDE model is also highly cited and reached more than 500 citations.
Most up-to-date experimental and modeling approaches, current trends, and future challenges in the investigation of the synergistic interplay of HE mechanisms in different grades of steel, including the most advanced, and iron, are also included and critically discussed. It also provides a "perspective" about what computational simulations and multiscale modeling of HE phenomena can and cannot do.

3 年Dr Milos Djukic Sir, Congrats for ur promotion as Professor, University of Belgrade. Sir,research on Hydrogen embrittlement was conducted under support n guidance left no scope fr modernisation n correction on mechanism of crack development by weakening grains structure by stress development n its fast propagation on metal body leading failures. Testing details n stress evaluation evaluation calculations been done under ur guidance followed by educated scientists n engineers researchers,admire their expertise efforts. But it needs attention metal manufacturing lacks left minor impurities,conditions during process with deviation in temp exceeding reccomended n also steam quality deviation. For any additional informations welcome. Thanks with sincere regards Ajoy Chatterjee
