Economic and sustainable production is among the most recent and enduring challenges being faced by the manufacturing area nowadays. The Additive Manufacturing (AM), capable of producing with flexibility, fully automation and sustainability, arises with a strong appeal to replace traditional processes such as casting, forging and conventional machining. AM technology was addressed in a wo…
The applicability of welding to advanced high-strength steels directly in the bainitic field was proven by a Research Fellowship Abroad (grant 2014/26930-7) of the applicant. As a means to internalize the technology and to apply to a broadly used aerospace material, this proposal seeks to experimentally develop the laser welding at high temperatures of maraging steels directly on the aged…
Lasers have attracted much attention for the materials processing, including in surface engineering. Among the various laser surface processing of materials techniques, this work will study five types: Laser controlled fracture is a micromachining method used to guide a crack through a desired path in order to create a controlled fracture. Microtexturing is a technique for changing the ch…

Gas turbine repair through additive laser manufacturing is an economically viable alternative due to the high value of these components. The present study aims to develop a laser direct energy deposition technique for the repair of stainless steel blades in order to return them to their common use. In addition to the additive part, the high speed machining technique will be used for surfa…
The development of small satellites has a direct impact on key sectors of national development, namely: telecommunications, environment, and particularly defense, integration and control of 22 million km2 by the Brazilian Air Force. The present research project aims to provide the Institute for Advanced Studies with a new research group for the design, manufacture and testing of small sat…
Molds and dies are essential tools in the development and manufacturing of a diversity of parts and components. However, the need for mold and die repair is a consequence of probable design and/or manufacturing errors, material defects, plastic deformation and wear. In turn, conventional arc welding repair processes prove to be insufficient with regard to design, dimensional requirements,…
The growing demand for research and development related to technological innovation in the aerospace sector has prompted the steel industry to design new material concepts for such an application. As excellent properties of Advanced High Strength Steels, especially TWIP (Twinning Induced Plasticity) steels, they make them promising for a fabrication of structural components of transport s…

Advanced high strength steels (AHSS) and ultra high strength steels (UHSS) have been used in a number of applications such as automobile construction and petroleum and natural gas pipelines. In the aerospace industry, these steels are suited for use in motor engines, landing gears and armoring. Although these metallic alloys are well known in terms of microstructure and mechanical and che…
