Passive films formed on stainless steels in phosphate buffer solution
(Springer, 2016)
The behaviour of passive films formed on directionally solidified stainless steels,18Cr10Ni2Mo0.08C, 18Cr14Ni8Mo0.03C and 18Cr10Ni8Mo0.08C, in different areas that wereformed during solidification (columnar, columnar-to-equiaxed ...
Influência da adição de cério na microestrutura e comportamento de oxidação de aços inoxidáveis Fe-Mn-Si-Cr-Ni com efeito de memória de forma
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2020-01-15)
In this study, the influence of small cerium additions on the microstructure and
oxidation behavior of Fe-Mn-Si-Cr-Ni shape memory stainless steels (SMSSs)
was investigated. The results show that the Ce addition in the ...
Propriedades mecânicas de tração e impacto dos aços inoxidáveis CA15 e CA6NM
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2007-02-27)
The subject of this work was to study the mechanical properties, based in tensile and impact tests, of two stainless martensitic steels cast under designations of ASTM Standards, namely the CA15 steel, a steel with 12% of ...
Influence of chloride ion concentration and temperature on the electrochemical properties of passive films formed on a superduplex stainless steel
(ELSEVIER SCIENCE INC, 2010)
Polarization measurements were conducted to monitor the corrosion behavior of superduplex stainless steel ASTM A995M-Gr.SA/EN 10283-Mat#1.4469(GX2CrNiMo26-7-4) when exposed to a) an electrolyte containing 22,700 parts per ...
Comportamento de fluência e tração a quente do aço inoxidável austenítico AISI 201LN
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2020-09-21)
Among the different stainless steel (SS) series, the 200 series, also known as Cr-Ni-Mn alloys, has recently been gaining prominence worldwide. In spite of that, studies addressing the high-temperature deformation these ...
Comparative study of Cr3C2-NiCr coatings obtained by HVOF and hard chromium coatings
(Elsevier B.V., 2006-10-01)
In the present work the corrosion resistance of micro-cracked hard chromium and Cr3C2-NiCr (HVOF) coatings applied on a steel substrate have been compared using open-circuit potential (E-OC) measurements, electrochemical ...
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 ...
