Austenite instability and precipitation behavior of high nitrogen stainless steels
(Nova Science PublishersNew York, 2016)
Nitrogen is a strong austenite stabilizer and improves the mechanical properties and the corrosion resistance of austenitic stainless steels. For these reasons, nitrogen addition to steel has been extensively studied in ...
Estudo de caso da utilização de aços inoxidáveis para aplicação em recuperadores de calor na indústria siderúrgica
(2021-12-08)
Dentre as aplicações de aços inoxidáveis, existe a fabricação de tubos sem costura para trocadores de calor, como em recuperadores em siderúrgicas. Em uma planta siderúrgica, por exemplo, processos que envolvem temperaturas ...
ASTM A923-Practice A application to identify intermetallic phases in a UNS S32750 superduplex welded joint
(ESCOLA DE MINAS, 2010)
Duplex and superduplex stainless steels present superior mechanical and corrosion properties when compared to usual stainless steels. This superiority is based on chemical composition when in a balanced microstructure ...
Selective reactivation of inherited fault zones driven by stress field changes: Insights from structural and paleostress analysis of the Pocuro Fault Zone, Southern Central Andes (32.8 degrees S)
(PERGAMON-ELSEVIER SCIENCE LTD, 2022)
This study aims to explain the selective reactivation of normal faults during the Andean orogeny at the Southern Central Andes western flank. We conducted a structural mapping and paleostress field reconstruction in the ...
Estudio del crecimiento de grietas por fatiga, la tenacidad a la fractura y la evaluación no destructiva de un acero inoxidable dúplex 2205 envejecido térmicamente
(Universidad Michoacana de San Nicolás de Hidalgo, 2014-06)
In recent years, the use of duplex stainless steels (DSS) has increased in the fabrication of in various engineering components for different production processes in the oil, nuclear and petrochemical industries. The reason ...
Caracterización no destructiva, microestructural y mecánica de acero inoxidable dúplex 2205 envejecido térmicamente
(Universidad Michoacana de San Nicolás de Hidalgo, 2012-08)
This research presents experimental results of non-destructive techniques to evaluate and monitor microstructural changes in a 2205 duplex stainless steel caused by aging treatments. Aging treatments were carried out between ...
