The ASTAR is an ultra fast system that can perform an acquisition between 5-10 min in an area of 5x5 microns (500x500 points) with dedicated CCD camera. When combined with the precession system allows obtaining maps of orientation and phases with extreme precision. When combined with a transmission electron microscope (Tecnai G2 F20 - EGF, with a resolution of 1.5 A), the ASTAR system can…
The specified atomizer allows the processing of low quantity of material (equivalent to 3kg Fe alloy) which is interesting considering the research purpose, and we will be studying a large number of alloys in various systems. Also the atomizer allows the fusion is made in vacuum or inert atmosphere, which ensures a desired purity in the alloy, as well as permitting the use of atomizing ga…
Metallic alloys with microstructures containing amorphous, metastable and nano-structured phases represent a new class of materials with surprising properties, which result both from intrinsic characteristics of the structure and from the presence and combination of phases produced by the compositions and by the different types of non-equilibrium processing techniques. In this context, th…

There is a great demand for more efficient electric motors, with less energy consumption and lower cost. Generally, the core of the electric motor is composed of thin sheets of Fe-Si alloy stacked alternately with layers of electrically insulating material, which is a strategy that aims the reduction of eddy current losses. The addition of 6.5%wt. of silicon in this alloy promotes optimiz…
Multi-Principal Element Alloys (MPEAs), complex and concentrated alloys, and medium and/or high entropy, are names of a new class of materials which main characteristic is not having a main element. Recent literature works points out the need to explore more complex routes and mechanisms for microstructural development in alloys that already have promising potential. An important refining…
Additive Manufacturing (AM) are processes where a part is built layer by layer based on a 3D model. This definition is widely applicable to all classes of materials including metals, ceramics, polymers, composites and biological systems. Among the processes used in the additive manufacture of metallic parts, we can highlight the Selective Laser Melting (SLM), which is a promising techniqu…

Multiprincipal, complex and concentrated, medium and/or high entropy alloys are different nomenclatures used for a new class of alloys that do not have a main element. Although hundreds of compositions have been produced to date, the compositional field of these alloys still remain mostly unexplored, especially regarding non-equiatomic compositions. Several compositions with superior prop…
High strength and good corrosion resistance are basic requirements for materials used in extreme environments such as those found in the petrochemical, aerospace and naval sectors. High Entropy Alloys (HEAs) have a very large compositional flexibility which gives these alloys a wide range of properties. An example is the alloy Cr33.3Co33.3Ni33.3 which is one of the toughest materials ever…

Medium/high entropy, Multiprincipal element alloys (MPEAs) have significantly increased the number of potential compositions of metallic alloys to unprecedented levels. In addition to discovering new compositions of interest, optimizing the most promising MPEAs is equally critical. The Cr40Co40Ni20 MPEA stands out by showing high mechanical strengthening via grain refining, and high work …
Bulk Metallic Glasses (BMGs) exhibit an aperiodic atomic structure without long-range order, which results in exceptional strength, large elastic limit, excellent magnetic properties, and good corrosion resistance. They are used as micromotors and precision gears for Micro Electro Mechanical Systems (MEMS), automobile valve springs, diaphragms for pressure sensors, power inductors, sporti…
The BEPE internship project proposed here aims to improve Santana's thesis by characterizing the high temperature mechanical behavior of previously designed precipitation-hardened HEAs through a Gleeble Thermal-Mechanical system. Besides, computational methods will be used to gain an in-depth understanding of the effect of iron additions on the antiphase boundary energy (APB) of Al-Ti-Cr-…
