Influence of sigma phase formation on pitting corrosion of an aged uns s31803 duplex stainless steel
(2013)
The main purpose of this contribution was the study of the relation between sigma formation and pitting corrosion resistance of a UNS S31803 duplex stainless steel aged at 850°C. Solution-treated samples were isothermally ...
Kinetic Study to Predict Sigma Phase Formation in Duplex Stainless Steels
(2016)
© 2016, The Minerals, Metals & Materials Society and ASM International.This work presents an improved kinetic study of sigma phase formation during isothermal aging between 973 K and 1223 K (700 °C and 950 °C), based on ...
Effect of Mo substitution by W on the passive characteristics and mechanical properties of AISI 316L austenitic stainless steel
(2019)
© 2019 NACE International.This work studied the influence on pitting corrosion resistance and mechanical behavior of the partial or total substitution of Mo by W in AISI 316L austenitic stainless steel. Alloys that contain ...
Influence of the Heterogeneous Nucleation Sites on the Kinetics of Intermetallic Phase Formation in Aged Duplex Stainless Steel
(2017)
© 2017, The Minerals, Metals & Materials Society and ASM International.The aim of this work is to study the influence of the heterogeneous nucleation site quantity, observed in different ferrite and austenite grain size ...
Reverse strain-induced martensitic transformation of the ferrite to austenite in duplex stainless steels
(2016)
© 2016, Springer Science+Business Media New York.The possibility of a reverse strain-induced martensitic transformation (RSIMT) of ferrite into austenite was evaluated in two duplex stainless steels (DSS) solution treated ...
Intermetallic phases formation during short aging between 850 °c and 950 °c of a superduplex stainless steel
(2012)
This paper is based on the study of intermetallic phase formation during aging between 850 C and 950 C, for periods up to 5 min; those treatments were conducted in liquid aluminum bath, allowing fast heating of the small ...
Low temperature active screen plasma nitriding of 17–4 PH stainless steel
(2016)
© 2016 Elsevier B.V.In the present work, low temperature active screen plasma nitriding of a 17–4 PH precipitation-hardening stainless steel was investigated. The active screen technique has been used to avoid undesirable ...
Tool wear evaluations in friction stir processing of commercial titanium Ti-6Al-4V
(2013)
This research addresses the application of friction stir welding (FWS) of titanium alloy Ti-6Al-4V. Friction stir welding is a recent process, developed in the 1990s for aluminum joining; this joining process is being ...
Lignin as additive in polypropylene/coir composites: Thermal, mechanical and morphological properties
(2012)
PP/CF composites were prepared and the effect of lignin incorporation in the presence and absence of compatibilizer (maleic anhydride grafted polypropylene, PP-g-MA) was investigated by means of mechanical, thermal and ...
Relation between pitting potential, degree of sensitization, and reversed austenite in a supermartensitic stainless steel
(2017)
© 2017, NACE InternationalPitting potential (Ep) and degree of sensitization (DOS) of a supermartensitic stainless steel (SMSS) were determined on specimens heat-treated at different tempering temperatures (550°C, 575°C, ...
