Laboratories
Activities: Basic and technological research of all aspects of self-reduction, principally the carbothermal reduction of metal oxides; the basic and technological aspects of tabletting processes, fusion-reduction processes; the obtainment of carbon composite briquettes; the obtainment and use of reducers using biomass; a reduction in the consumption of energy and the generation of greenhouse gases in metallurgical processes; the use of microwave energy in metallurgical processes; the recovery of metals from industrial waste.
Activities: The main activities of the laboratory are the various didatic activities for undergraduate studies, especially in subjects such as Phase Transformation in Metals, Selection of Materials, Failure Analysis, Ceramography and Metallography. Additionally, the laboratory offers basic facilities for graduate students and consultancy work in areas such as corrosion, failure analysis, welding and microstructural optimization.
Activities: The materials engineering computer laboratory is equipped with two personal computers and is registered together with the advanced scientific computer laboratory of the electronic computer center of the University of São Paulo, with a view to the use of the resources available at this institution.
Activities: The analysis of materials, particularly polymers, with a view to using the same in sustainable technologies, including biomaterials, biodegradable products, organic solar cells and electroluminescent organic devices, among others.
Activities: The scope of LMPSol is based on well consolidated lines in the research of scientific and technological aspects involving clays, clay minerals, industrial minerals, traditional ceramic materials and glass. Furthermore, other lines of research in connection with the environment are under development: tge treatment and recycling of solid waste and the disposal of hazardous waste from industrial chemical processes.
Activities: This laboratory is equipped for microstructural testing on a micrometric and nanometric scale.
Activities: The laboratory for the milling of high energy carbon materials and composites for high temperatures (LM²C²/USP) strives to develop new materials and composite materials containing carbon as part of the matrix and associated system for use in environments where processes of corrosion and oxidation degrade and undermine the life of devices, components and chemical reactors. The laboratory researches the production of metallic materials and metal alloys produced by high-energy milling based on aluminum-silicon-magnesium, SIALONs, titanium and boron as antioxidant agents and/or precursors of carbides and borides for use in high temperature, with the objective of protecting the carbon, such as soot, graphite, solid tar, nanotubes and graphene as a mean of optimizing the thermal, chemical and mechanical properties of oxide-carbon composites and refractory materials used in high temperatures. Other lines of research include the catalytic modification of the graphitization process of resins/polymers, the deposition of carbon, and the risk analysis of the safe handling of nanomaterials, nanofibers and metallic nanoparticles and nanocarbons.
Activities: The laboratory conducts research focused on: surface and colloid chemistry applied to evaluate the stability of ceramic suspensions; synthesis of nanometric ceramic powders via chemical routes; sintering of nanometric powders and processing of ceramics; shape-forming in regards to possible applications in chemical, metallurgical, electrical and electronics and civil engineering.

Activities: The LPE laboratory is equipped to conduc testing for the analysis of corrosion in metallic materials, largely based on polarization curves and loss of mass.The H2S laboratory forms part of the LPE laboratory and is designed to the study of corrosion and embrittlement in pipeline steels in special gases.
Activities: The purpose of the materials engineering simulation laboratory is the development of the mathematical models for the analysis of the phenomena which occur in the processing of materials. Most of the work performed in this laboratory is related to the modeling of transport phenomena and phase transformation, as is the case of the solidification of metals.
Activities: The research produced in this lab are focused in developing the relationship between welding process, welding metallurgy and welding behaviour of metallic materials (ferrous and non-ferrous alloys) and polymeric materials.The main research lines of Welding and Joining Laboratory are: physics of arc welding and resistance welding; welding of high resistance low alloy steels (AH36 and API 5L X80 and higher grades), low alloy steels (Cr-Mo, Cr-Mo-V, Ni based steels) and stainless steels (lean duplex, duplex, super duplex, hyper duplex, austenitic, ferritic and martensitic); welding 'in service'; welding of alluminum alloys; arc welding processes; resistance welding processes; brazing; soldering for electronic applications; welding of polymers by ultrasonic process.
Activities: The research projects conducted by this laboratory aim to combine global methods for monitoring phase transformation with local methods of direct observation. Examples of global methods are measurements of physical and mechanical properties, dilatometry, thermal analysis, X-ray diffraction, etc.Examples of local methods are metallography techniques applied to optical and electronic microscopy.
Activities: The main reseacrh activities conducted in the Polymer Materials Processing and Polymer Mixture and Transforming Materials Laboratories are: Linear and Nonlinear Viscoelasticity of Polymers Blends; Interfacial Tension in Polymer Blends; Nanocomposites and Plasma Modifications of Surfaces.
