Hydrogen Embrittlement - Understanding and research framework, online Project on ResearchGate (80+ members, 210+ followers, 2400+ reads, 40+ updates)

Link: https://www.researchgate.net/project/Hydrogen-Embrittlement-Understanding-and-research-framework

Dear colleagues and friends,
I started this online Project on ResearchGate (2016) as an extension of the former Hydrogen Embrittlement Mechanism Project on ResearchGate (2014) which was very successful and with an idea that the top experts in the field of hydrogen embrittlement and materials science come together and share valuable experiences about the current state of the art in hydrogen embrittlement.

Numerous prestigious experts in the field of hydrogen embrittlement and materials science are the project participants. This Project is only accessible to the Project members, making them an ideal place for private and secure data sharing, real-time feedback and scientific collaboration.

I cordially invite all interested researchers, engineers and technicians in the field of materials science, materials characterization and hydrogen embrittlement to join and follow “Hydrogen Embrittlement – Understanding and research framework” Onlline Project on ResearchGate.

Best Regards,
Milos Djukic

Dear colleagues, I hope that some of you find this work interesting:

Strain gradient plasticity-based modeling of hydrogen environment assisted cracking

Emilio Martínez-Pañeda, Christian F. Niordson, Richard P. Gangloff

Acta Materialia, 117, pp. 321-332

http://www.sciencedirect.com/science/article/pii/S1359645416305183

A pre-print is available at www.empaneda.com

Finite element analysis of stress about a blunt crack tip, emphasizing finite strain and phenomenological and mechanism-based strain gradient plasticity (SGP) formulations, is integrated with electrochemical assessment of occluded-crack tip hydrogen (H) solubility and two H-decohesion models to predict hydrogen environment assisted crack growth properties. SGP elevates crack tip geometrically necessary dislocation density and flow stress, with enhancement declining with increasing alloy strength. Elevated hydrostatic stress promotes high-trapped H concentration for crack tip damage; it is imperative to account for SGP in H cracking models. Predictions of the threshold stress intensity factor and H-diffusion limited Stage II crack growth rate agree with experimental data for a high strength austenitic Ni-Cu superalloy (Monel®K-500) and two modern ultra-high strength martensitic steels (AerMet™100 and Ferrium™M54) stressed in 0.6 M NaCl solution over a range of applied potential. For Monel®K-500, KTH is accurately predicted versus cathodic potential using either classical or gradient-modified formulations; however, Stage II growth rate is best predicted by a SGP description of crack tip stress that justifies a critical distance of 1 μm. For steel, threshold and growth rate are best predicted using high-hydrostatic stress that exceeds 6 to 8 times alloy yield strength and extends 1 μm ahead of the crack tip. This stress is nearly achieved with a three-length phenomenological SGP formulation, but additional stress enhancement is needed, perhaps due to tip geometry or slip-microstructure.

Dear Colleagues,

At present the Government of Russian Federation announced open competition for providing federal support for research conducted under leading scientists` supervision. The Government of Russian Federation grants are allocated in the sum of ~1.1 million Euro (at current exchange rate) each for conducting research for three years from 2017 including 2019 with the possibility for prolongation of research for up to two years. Please find the information about the open competition in the attachment to this email; you may also follow the link: http://www.p220.ru/en/.
We would like to propose you to take part in this competition in collaboration with Tomsk Polytechnic University. The research team of the Department of General Physics already has wide experience in realization of several projects run as a result of the award within analogous open competitions. Please follow: http://www.p220.ru/en/11-g34-31-0002 and http://www.p220.ru/en/home/projects/item/281-11-g34-31-0003

The research teams of the Department of General Physics and the Laboratory and I will be honored if you consider our invitation to take part in this open competition as a leading scientist for the future project. Themes for the project may be various, however the Laboratory is mainly engaged in research in hydrogen materials science and non-destructive testing (http://tpu.ru/en/structure/institutes/pt/gp/).

Possible research topics are the following:
1. Hydrogen embrittlement of structural materials
2. Hydrogen protective coatings and surface modification
3. Hydrogen storage materials
4. Additive technologies for metals and alloys
5. Development and application of methods of positron spectroscopy (including positron beams)
6. Non-destructive testing of hydrogen embrittlement

The deadline for submission of grant applications is 12:00 Moscow time on May 31, 2016. Grant competition winners will be identified by November 30, 2016 in compliance with the relevant procedure accounted for by the competition documentation.
Looking forward to your reply and prospective collaboration.

If you know any scientists who might be interested in similar projects, please share with them the information about the opportunity to participate in federally sponsored research if winners within this competition.

If you have any questions please contact us:

Hydrogen Embrittlement Network - introduction

"The Network of Excellence (NoE) in Hydrogen Embrittlement aims to strengthen scientific and technological excellence by developing an integrated and interdisciplinary scientific understanding of hydrogen degradation of engineering materials and their co-evolution with science, materials science, industry and society, and also by addressing the fragmentation of European and Worldwide research in this area".

http://milosdjukichydrogen.wordpress.com/2014/05/14/the-network-of-excellence-noe-in-hydrogen-embrittlement/

The benefits of this network are available to all interested researchers, scientists, professionals and practitioners. Without your participation, Dear colleagues, this network would not be successful.

Frontiers in Materials Journal - Corrosion Research section - Hydrogen Embrittlement Mechanisms topic

Dear colleagues,

In collaboration with Frontiers in Materials Journal, within Corrosion Research as a specialty section of Frontiers in Materials, we are organizing a Research Topic titled “Hydrogen Embrittlement Mechanisms”, hosted by Milos Djukic and Andrej Atrens. As topic editor, I would like to encourage you to contribute to this topic.

The idea behind a research topic is to create an organized, comprehensive collection of several contributions, as well as a forum for discussion and debate. A brief description of the topic is provided on our homepage on the Frontiers website (section “Corrosion”). This is also where all articles will appear after peer-review and where participants in the topic will be able to hold relevant discussions:

http://www.frontiersin.org/corrosion_research/researchtopics/hydrogen_embrittlement_mechani/2922

Frontiers, a Swiss open-access publisher, recently partnered with Nature Publishing Group to expand its researcher-driven Open Science platform.
