Turbine discs are critical components of jet engines in the aerospace industry. The severe environmental conditions found in the hot parts of the jet engine imply that components should have good oxidation/corrosion resistance, especially considering the important damage that these processes can cause, including their effects on the mechanical behavior of the material at high temperatures…
The b-21S titanium alloy corresponds to one of the main titanium alloys for structural applications at high temperatures. Its nominal composition is Ti-15Mo-2,7Nb-3Al-0,2Si (% by weight) or near Ti-8Mo-1.5Nb-5,7Al-0.6Si (% atomic). There is no systematic data on the literature on the possible microstructures developed in this alloys; its mechanical properties and oxidation resistance. Par…
Materials applied at high temperatures and severe environments became a scientific and technologic requirement nowadays. Literature relates studies that have been done independent of commercial objectives to improve the development of new alloys and, in particular, to reevaluate the existent commercial alloys, through data acquisition in extreme conditions. This innovator postdoctoral pro…

Good oxidation resistance at high temperatures is a fundamental feature that a structural material must present for structural applications at high temperatures. Recent investigations carried out by our research group have shown the beneficial effect of replacing Ti for Nb terms of oxidation in Ni-based superalloys. In the present proposal, we also intend to evaluate the effect of this re…
This work aims to apply aluminum-based coatings to improve the corrosion resistance of the cleaning tip, a device used in Kraft recovery boilers for the production of cellulose, used to unblock the air flow ports. Corrosion is one of the main causes that shorten the useful life of steam generating plants. According to HAMAGUCHI and VAKKILAINEN (2010) Corrosion problems in boilers can cost…
Metal alloys are commonly applied in biomedical applications when properties like high strength and high fracture toughness are required. For this class of materials, stainless steel, titanium and cobalt-chrome alloys are the most used today. However, these alloys may exhibit limitations for certain applications, especially in situations when the biodegradation of the implant is desired.…
Magnesium alloys are indicated as potential biodegradable biomaterials, since they have good biodegradability, biocompatibility and satisfactory mechanical properties. When compared to metal alloys used in permanent implants, ceramic and polymeric biomaterials, magnesium alloys are characterized by low specific mass and better results in load applications due to the combination of high me…

Jet engines correspond to complex machines, being used in the propulsion of airplanes and electric power generators. In the turbine region of these machines, very high temperatures are reached, and several components are subjected to high levels of stress, such as the discs. To obtain greater engine efficiency, with a reduction in fuel consumption and pollutant gas emissions, the inlet te…
