  This proposal goes within the context of a request for a Visiting Researcher Grant, with the general objective of fostering the exchange and scientific cooperation between two research groups, a Brazilian and Franco-Emiradian, which have a substantial role in the study of corrosion properties of several innovative alloys. Among these alloys, High Entropy Alloys (HEA) have attracted increa…

• Abstract

  The application of ECAP can be restricted during the processing of hard-to-deform and low-ductility materials. It is known that in order to effectively refine the structure and achieve superior properties ECAP should be realized in several cycles. The high level of accumulated strain can result in crack initiation and failure of samples, which is connected with non-conformance of ductilit…

• Abstract

  Mg2FeH6 and Mg2CoH5 are promising means for solid state hydrogen storage because they have high gravimetric and volumetric storage densities. However, these complex hydrides are not easily synthesized as a single phase material. Interesting results of synthesis of these phases have been obtained using reactive milling under hydrogen atmosphere, producing nanocomposites with promising prop…

• Abstract

  Conventional implants perform satisfactorily in many cases. However, due to their inert characteristic, there is no satisfactory interaction with the body. The frequent causes are infections, inflammation, allergic, and necrosis responses, leading to device rejection. Three critical requirements must be considered for the correct interaction: 1) Minimize stress shielding, which is due to …
