High entropy alloys are multicomponent alloys that, unlike classic alloys such as nickel steels and superalloys, do not have a principal element, each of its components composing the alloys in contents between 5 and 35 at.%. One of the possible branches of application for these alloys is the aeronautical industry, particularly those made of high melting point and low density metals, where…
Goal: This project aims to develop new compositions of materials (structural and coating) made from niobium for high temperature applications (HT). The goal is to contribute to the development of a thermodynamic database system (Nb)-(Fe-Cr-Al-Y-Ru-Si-B) to define the compositions of pairs of substrate/coating having an excellent resistance to HT oxidation. Background: The development of m…

The study of kinetic phenomena is important in order to understand physical-chemical and mechanical properties of materials, such as creep, corrosion and oxidation resistance. One of these phenomena is the diffusion, whose processes are widely explored in many industrial sectors, for example in surface heat treatments to improve some properties. The deposition of oxidation protective coat…
High Entropy Alloys containing Al and refractory metals are promising structural materials for aeronautical applications, complementary to Ni-based superalloys. The knowledge of the phase equilibria in the Al-V-Zr system corresponds to an important contribution to the development of these alloys, especially for research related to the development of thermodynamic databases. In the present…
Since the beginning of the 21st century, a new concept of alloys has attracted the interest of the scientific community. These are alloys with multi-principal elements, which are also known as high-entropy alloys. Considering the necessity of new materials for advanced high-temperature applications, refractory metals have been used as constituents of such alloys. Later, aluminum was added…
Since the beginning of the 21st century, a new concept of alloy development has attracted the interest of the scientific community. These are alloys with multi principal elements, which are known as high entropy alloys. Considering their potential application at high temperature, refractory metals have been used as constituents of such alloys, known as refractory high entropy alloys. Furt…
High-entropy alloys (HEA) containing Al and refractory metals are promising structural materials for aeronautical applications, complementary to Ni-based superalloys. The knowledge about the phase relations in the Al-V-Zr system corresponds to an important contribution to the development of these alloys, especially for the development of thermodynamic databases.

The development of new materials with low density and stable mechanical properties at high temperatures is necessary to reduce fuel consumption and gas emissions in the aerospace industry. HEAs (High Entropy Alloys) are a new class of materials that combine elements with high melting point and aluminum and can be candidates for this development. Phase diagrams are a necessary tool for the…

Since the beginning of the 21st century a new concept of metal alloy development has attracted the interest of the scientific community. These are alloys with multi main elements, which are also known as high entropy alloys. Considering the need for new materials for advanced high temperature applications, the refractory metals have been used as constituents of such alloys. In this way, h…
Phase equilibria data of the Al-Nb-V system are important for the design of innovative, low-density, Al-containing refractory high-entropy alloys. The scholarship candidate, MSc. Júlio César Pereira dos Santos, started the studies in this system in his master work determining the isothermal section at 1200 °C and performing a preliminary thermodynamic modelling of the system using microst…
