Análise de microestrutural, de resistência à corrosão e de microdureza do aço A...
Silva Junior, Francisco Carlos Gomes da; Rodrigues, Matheus Souza; Mata, Stephany Aparecida Santos da; Machado, Janaína Gonçalves Maria da SilvaASTM 890 grade 3 stainless steel duplex (AID) has great use in the oil tube industry in Brazil and worldwide. The material of the time variation necessary to solubilize a material is important, therefore, by decreasing this time, it can become spent with an furnace. The objective of this paper is the comparison of results for the different solubilization times of ASTM 890 grade 3A molten duplex stainless steel....
Corrosion Resistance of Cu-Alloyed Precipitation Hardenable Duplex Stainless St...
Lima, Hillane Mirelle Lopes Ferreira de; Tavares, Sérgio Souto Maior; Bastos, Ivan Napoleão; Rodrigues, Matheus Souza; Martins, MarceloDuplex stainless steels (DSS) are corrosion resistant alloys largely used in chemical and petrochemical industries. Some commercial DSS contain 0.5-1.0% copper addition to improve the corrosion resistance by reducing the corrosion rate in non-oxidizing environments. Higher copper addition (≥ 2%) can also hard by precipitation, especially when fine copper precipitates (ε phase) are produced. In this work, a cast...
Estudo da eficiência de um inibidor à base de amina nos sistemas de CO2 E CO2-O...
Rodrigues, Matheus SouzaMetallic materials present a wild field of application in the most diverse industries. One of them is oil and gas, which uses carbon steel for pipelines in transport and material extraction. However, the environment in which these materials are located are quite corrosive, bringing costs with maintenance and replacement of components. Some measures are used to improve corrosion resistance of the metals. The mos...
