The project aims to incorporate a specialized holder for in-situ analyses, allowing precise control of temperature and electrical potential. The holder will be obtained with a permanent license for the AXON Synchronicity software, which provides motion correction for thermal effects, enabling stable analyses at nanoscales. Additionally, the project includes the acquisition of an 80mm Ener…
High/medium entropy alloys (HEAs/MEAs), or multi-principal element alloys (MPEAs), are emerging materials that are gaining notable interest. Several MPEAs combine high strength, ductility, fracture toughness, and resistance to oxidation, corrosion, and radiation. One of the most notable alloys in this regard is the CoCrNi alloy. This makes MPEAs suitable for sectors such as biomedical, en…
Over the past few years, computational algorithms have been introduced into almost every aspect of our lives, optimizing problem-solving processes at unprecedented speeds. In parallel, a new class of metal alloys, the so-called High Entropy Alloys (HEAs), which main feature is not having a single main element, has been attracting the attention of researchers in recent years. The vast fiel…

Multi-Principal Element Alloys (MPEAs) are metallic alloys that do not have a single main element which yields an immense number of possible compositions. Despite this, several alloys with interesting sets of properties have already been found. The featured compositions include those of the Cr-Co-Ni system, which are among the toughest materials ever developed, which can be attributed to …
Due to the large number of possible compositions, medium- and high-entropy alloys exhibit a broad spectrum of mechanical and functional properties when compared to traditional alloys, including magnetocaloric properties. The first magnetocaloric high-entropy alloys contained rare-earth elements in their composition, but recently, alloys without these elements have been developed. The MnNi…
This project aims to develop and optimize high-entropy alloys (HEAs) with magnetocaloric effects (MCE) for application in sustainable magnetic refrigeration technologies. Considering that current refrigeration solutions based on gas compression cycles face environmental and efficiency challenges, the use of solid, emission-free magnetocaloric materials offers a promising pathway. To addre…

The project aims to study the synthesis and characterization of high-entropy alloys (HEAs) in the (CrFeCoNi)-(SiGe) system to investigate their magnetocaloric properties and potential for applications in efficient magnetic refrigeration. These alloys, which contain multiple elements in equimolar proportions, have high mixing entropy and have shown great potential to replace conventional r…
With the increasing technological advancements, there is a need for the development of new materials. Among them, multi-principal element metallic alloys emerge, which do not have a single element as the main component but a combination of elements aimed at specific properties. In this current project, we will use genetic algorithms to select alloys with good mechanical strength and ducti…
Artificial intelligence algorithms play a crucial role in the learning process by analyzing and training predictive models based on data. The quality and diversity of data used in training are determining factors in the predictive capacity of the model. The more comprehensive and varied the data, the greater the accuracy and flexibility of the algorithm. In this specific project, we will …

The project aims to complement the characterization of a precipitation-hardened high-entropy alloy (HEA) from the Ni-Fe-Cr-Al-Ti-Nb system, previously developed with the aid of high-throughput CALPHAD methods. The alloy exhibits high mechanical strength and potential for additive manufacturing applications. To simulate such processing conditions, laser surface remelting will be performed …
In 2004, a new class of metallic alloys was introduced: High Entropy Alloys (HEAs). These alloys are defined by their composition, containing multiple principal elements, where each constituent can be considered a solute. The thermodynamic equilibrium of this alloy family is attributed to an increase in configurational entropy, which stabilizes a single-phase alloy. During their developme…
The ever-advancing pace of technology is driving the imperative need for the development of novel materials capable of fulfilling the evolving demands across various service sectors. In this dynamic landscape, High Entropy Alloys (HEAs) emerge as a notable solution. However, a significant challenge lies in the selection of optimal compositions from within a vast and complex multicompositi…
The BEPE internship project proposed here aims to improve Caroline's work by performing advanced X-Ray characterization of previously designed multicomponent alloys selected by a genetic algorithm partly developed, implemented, and used by Caroline in her FAPESP project. The algorithm designs strong MPEAs by combining different models to find optimized compositions. One crucial step is us…
Whit the results obtained until now, we have two unresolved questions: i) What is the origin and the nature of certain phases which does not show any electron diffraction pattern when evaluated by transmission electron microscopy on diffraction mode; ii) The presence of oxygen was confirmed by measurements of a LECO equipment and by the decrease in the glass forming ability, however it co…
