Quantificação de fases de um minério de ferro utilizando difração de raio-X e r...
Dias, Diego Henrique Fonteles; Klug, Jeferson Leandro; Machado, Janaína Gonçalves Maria da Silva; Bentes, Miguel Angelo da GamaThe characterization of iron ores is of great importance for their application in the production of the iron ore sinter. Obtaining information on the crystallographic properties, identification and quantification of phases present in the ore and crystallite size are information that can be valuable when it is desired to compose a mixture that will be sintered. In this work, X-ray diffraction and Rietveld's refi...
Influência da temperatura na resistência à corrosão por CO2 DO aço 904L
Dias, Diego Henrique Fonteles; Cardoso, Jorge Luiz; Lima Neto, Pedro de; Silva, Marcelo José Gomes daThe resistance to corrosion by CO2 of 904L superaustenitic steel was investigated using the technique of linear polarization. Heat treatments were performed on samples of 904L steel to simulate the effect of temperature on the resistance to corrosion by CO2. The temperature selected to heat treatments was 760ºC. Samples in the as received condition were also evaluated. The samples were immersed in artificial wa...
Estudo em laboratório de misturas para o desenvolvimento do sínter metalúrgico
Dias, Diego Henrique FontelesThe sínter, together with the steel coke, is the main input for the production of pig iron in the blast furnace, so develop methodologies that evaluate how the raw materials that constitute it interact through each other, by evaluating the phases that were formed. During the síntering process, it is relevant for the elaboration of good practices that favor the improvement of metallurgical sínter quality during ...
