The influence of He bubble in strengthening of Copper


Materials at Extremes

It is good to see that scientists are working hard to better evaluate the effect of He bubbles in metals and alloys!

Sharing a very interesting new article showing unequivocally the influence of He bubbles in the strengthening behavior of Copper! By using shock loading, Lear et al. discovered that He bubbles totally collapse, leaving monoatomic He behind, which then impedes deformation and embrittles the material. A significant work for the advancement of He bubbles influence on mechanical properties!

On this context, we have also investigated before the influence of Ar bubbles in the mechanical behavior of WTaMoV refractory high-entropy alloys, showing that Ar bubbles also contribute to strengthening of the material.

Original flyer of the event

The thematic axes program is an endeavor of the Universidade de Sao Paulo, started in the present year and has the aim to provide institutional responses of the major university in Latin America in 11 important themes: Agriculture, Inequality, Democracy, Cities, Culture & Art, Education, Economy, Energy, Industry, Environment and Health, in view of the United Nation’s Sustainable Development Goals.

I am included in the thematic axis Energy and I am there mainly to represent Nuclear Energy, last Thursday, however, I attended another action of the group, the workshop which had the same title as the one I used in this post, just in the Portuguese language.

In this workshop we received Prof. Plinio Nastari and Dr. Antonio Stuchi to talk about Biofuels. Prof. Nastari, among others, is professor at Harvard and Dr Stuchi works at Raizen, one of the leading producers…

Controlling radiation damage in nanomaterials


cgschoen

Nanomaterials are offering unique opportunities for the design of future nuclear materials. In our recent paper at ACS Applied Nano Materials, we demonstrate that AISI-316 steel nanoparticles are capable of self-healing from the deleterious effect of heavy-ion collisions.

We also pose a new question to the materials community on the recyclability of potential nuclear nanomaterials.

Four decades of research on high nitrogen steels at ETH Zürich! — Materials at Extremes


In the late eighties and early nineties, the ETH Zürich researchers worked intensively on the development of high nitrogen steels at the Institute of Metals Research – with some success. The result was important patents with industrial partners. A number of such steels are still in use today, in particular the nickel-free austenitic steels used […]

Dear colleagues and friends,

I am pleased to inform you that the three comprehensive review papers about hydrogen embrittlement phenomena, foresaw in this special issue (SI) are published. They will be collected soon together with other papers within the dedicated webpage about this SI.

1.
by Milos B. Djukic, Gordana M. Bakic, Vera Sijacki Zeravcic, Aleksandar Sedmak and Bratislav Rajicic
The particular emphasis in this paper 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. 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.

The role of atomistic simulations in probing hydrogen effects on plasticity and embrittlement in metals
by Ali Tehranchi and William A. Curtin
The authors pointed out that because of their limitations, atomistic simulations may not be definitive, but they nonetheless provide considerable insight by supporting or contradicting conjectures and concepts proposed to rationalize experiments. In this review paper, the broad range of issues is discussed in more detail and also including previously unpublished studies on the effects of hydrogen on the bowout of the edge dislocations in iron and predictions of solute- drag by hydrogen in nickel. It also provides a “perspective” about what computational simulations and multiscale modeling of HE phenomena can and what they cannot do.

Overview of metastability and compositional complexity effects for hydrogen-resistant iron alloys: Inverse austenite stability effects
by Motomichi Koyama, Cemal Cem Tasan and Kaneaki Tsuzaki
The authors simultaneously investigate two alloy-design strategies for hydrogen-resistant steels: the effect of ε-stability and effect of compositional complexity. This review paper introduces further details and highlighting the importance of compositional complexity for hydrogen resistance.

Master Internship:

“Hydrogen-embrittlement susceptibility of different grades of stainless steel”

Original text by Prof. Gilbert Hénaff:
The reduction of emissions is a major challenge for our society, which impacts in particular all activities concerned by mobility. As more particularly regards the automotive industry, the use of a carbon-free energy vector such as hydrogen gas represents a solution that has already been fairly widely deployed in Japan in particular. However, this technological solution raises the question of the compatibility of materials used in different parts of the vehicle vis-à-vis the exposure to high pressures of hydrogen gas. Indeed, it is well known that hydrogen dissolved in a metal can significantly reduce certain mechanical properties: this phenomenon is generally described by the generic term “Hydrogen Embrittlement” (HE). Since the control of the safe operating domain of components exposed to gaseous hydrogen partially conditions the viability of this technological solution, it is therefore essential to improve the understanding of the interactions between the exposure to gaseous hydrogen and the elementary mechanisms of deformation and damage.
The objective of the proposed internship is to study the embrittlement of different grades of stainless steels by gaseous hydrogen, and especially to understand the mechanisms of embrittlement according to the grade considered. A bibliographic study will be necessary, especially on the use in hydrogen of non-austenitic grades, characterized by a lower hydrogen solubility associated with a higher diffusion coefficient. Furthermore, an experimental the tensile behavior of different grades will be characterized on the H2 HYCOMAT test rig for variable exposure conditions (pressure, strain rate, temperature, etc.). The results will first be used to determine embrittlement indices. Beyond this, the analysis of these data, together with a micro-fractographic examination, will aim to define the areas of HE sensitivity and to identify the influencing factors in order to progress in the understanding of the hydrogen-induced damage mechanisms.
Techniques to use:
– Mechanical testing machines;
– Optical microscopy
– Scanning electron microscopy
The internship will be mainly mainly carried out at the Pprime Institute in partnership with UGITECH. However, UGITECH can provide its expertise on metallurgical characterization (micrographs, inclusion analysis, residual martensite measurement, etc.), which will require displacements on the Ugine site.

The 3rd International Conference on Metals and Hydrogen “SteelyHydrogen2018” gathered 177 participants from 27 countries. The conference focused on hydrogen embrittlement of metals with a targeted balance between academic research and industrial experience. The expanded scope, including aluminium, titanium and nickel based alloys, resulted in highly appreciated dedicated sessions on these topics. We are convinced this opened new perspectives in providing insights with regard to hydrogen related issues.

For further information about the position, please contact: Professor Afrooz Barnoush, (afrooz.barnoush@ntnu.no), a prominent expert in the field of degradation of materials mechanical properties under simultaneous effect of mechanical loading and environments like hydrogen embrittlement or stress corrosion cracking.

Postdoctor position description (short version):

Advanced high-performance materials are the enabling building blocks for the progress in all aspects of the technology. One important property of advanced materials which is extremely hard to study is their resistance to environmentally assisted cracking (EAC) in harsh conditions such as one existing in the marine environment. This is because mainly EAC resulted from the simultaneous interaction of three different domains of materials, environment, and mechanical loading.
in the past five years, many high-strength alloys, particularly precipitation-hardening nickel alloys and high strength steels, have been found prone to EAC, even in environments deemed a priori benign. In this project, we are intended to further consolidate our understanding of the EAC towards the development of a predictive multiscale model.
  • Qualifications:
The applicants must hold a PhD degree within materials science engineering or equivalent. Previous knowledge and experience in Nanomechanical testing with nanoindentation system, in situ nanomechanical testing in scanning electron microscope, focused ion beam microscopy as well as atomistic simulation with embedded atom potentials will be considered an advantage.
  • Conditions:

Postdoctoral candidates are remunerated in code 1352, and are normally remunerated at gross from NOK 485 700 per annum before tax. There will be a 2% deduction to the Norwegian Public Service Pension Fund from gross wage.

The appointment of the Postdoctoral fellows will be made according to Norwegian guidelines for universities and university colleges and to the general regulations regarding university employees.

The Postdoctoral fellowship is awarded for 2 years.
