One of the main challenges in the field of energy storage is the development of materials that can store hydrogen at ambient temperature. The objective of this project is to evaluate critically the alternative of processing Mg or Ti-based composites by severe plastic deformation, by high-pressure torsion (HPT) to develop new functional materials with superior properties for hydrogen stora…
Professor A. Inoue is one of the most important scientists involved with the area of development of metallic alloys processed in conditions far-from-equilibrium, which are the amorphous, nanocrystalline and quasicrystalline alloys. The activities during his visit of 45 days in the research group of Amorphous and Nanocrystalline Metals from DEMa UFSCar, coordinated by the responsible of th…

Stainless steels of different classes had their composition modified by the addition of boron, aiming to obtain amorphous phases and the controlled formation of borides. The formation of amorphous phase and the formation of borides aims to optimize the properties of alloys to be used for special coatings, specifically, with high resistance to corrosion and wear. Depending on the system, c…
Quasicrystalline alloys exhibit interesting features to be used as coatings due to high hardness, low friction coefficient, low friction coefficient (that is, a material with non-stick property), high corrosion resistance in acid medium, high resistance to oxidation and low thermal conductivity. The petrol industry has major problems associated with corrosion, wear and formation of organi…

With the increase in life expectancy, and the consequent ageing of the population the use of biomaterials is becoming increasingly necessary to replace or assist human body parts eventually lost or deteriorated. Ti and Ti alloys have played an important role in this area, because in addition to biocompatibility, mechanical properties usually need to be high, to satisfy mechanical demand, …

The research project to be developed during the period as visiting researcher at the Institut National Polytechnique de Grenoble, INP-Grenoble, at the Laboratoire d' electrochimie et de physico-chimie des matériaux et des interfaces, LEPMI, and Laboratoire Science et Ingénierie des Matériaux et des Procédés, SIMAP, is focused on the current research activities of the proponent in metallic…
Quasicrystalline alloys exhibit a variety of interesting properties, including high hardness, low friction coefficient, high corrosion resistance in acid medium, high resistance to oxidation and low thermal conductivity. Such features make the quasicrystalline forming alloys suitable candidates to be used as coatings, for example, in the petrol industry, which has major problems associate…
Non-equilibrium processing (NEP) of metallic alloys has been target of scientific investigation and technological developments to obtain metallic alloys with amorphous, quasi-crystalline and nano-sized microstructures (AQN) by combining specific compositions and high cooling rates. Due to their higher corrosion and wear properties, these metallic alloys can be used in many technological a…
