Duplex stainless steels (DSSs) are used in the chemical and petrochemical industries due to their good mechanical properties and high corrosion resistance. Lean duplex steels contain lower nickel and molybdenum contents compared to conventional DSSs and present strain-induced martensite transformation (SIM). In this project, UNS S32304 lean duplex steel will be investigated, cryorolled at…
In this work, the UNS S32304 lean duplex stainless steel will be investigated. Due to the combination of good mechanical properties and corrosion resistance, this steel has applications in both chemical and petrochemical industries. Strain-induced martensite (SIM) forms upon cold rolling in this steel. The main focus of this project is the study of austenite reversion after cold rolling a…
In this project, two Fe-Mn-C steels (1.5% Mn and 17% Mn) will be investigated with regard to their microstructural evolution and magnetic properties. For these two steels, the so-called Transformation-Induced Plasticity (TRIP) effect is expected to occur with greater intensity for the steel containing less manganese. The main focus of this work will be on the formation of the strain-induc…
This project aims to investigate the microstructural evolution and its effects on magnetic and electric properties of two distinct stainless steels: ODS-Eurofer steel and AISI 201 steel. ODS-Eurofer ferritic-martensitic steel is a potential candidate for structural applications in fusion reactors. AISI 201 austenitic stainless steel replaces AISI 304 steel in applications that demand a lo…

Duplex stainless steels have a microstructure composed of alternating austenite and ferrite lamellae, with approximately equal volume fractions. Due to the combination of good mechanical properties and corrosion resistance, these steels are used in a range of applications in the chemical and petrochemical industries. Compared to austenitic stainless steels, few works report on the microst…
In this Scientific Initiation project, the austenitic reversion in a UNS S32304 lean duplex stainless steel rolled at 77 K will be investigated. Due to the combination of good mechanical properties and corrosion resistance, this steel is used in the chemical and petrochemical industries. This steel exhibits strain-induced martensite (SIM) formation. Recent works by our research group repo…
In this project, the microstructural evolution and magnetic properties of two Fe-Mn-C (1,5%Mn and 17%Mn) steels will be investigated. For these steels the TRIP effect (Transformation-Induced Plasticity) is expected to occur with high intensity for the one with lower content of manganese. The main focus of this work will be on the strain induced martensite (and its reversion). Besides, th…
In this project we aim to investigate the recrystallization of low carbon steel (ABNT 1012) deformed by a single pass of equal channel angular extrusion. After deformation (von Mises equivalent strain of 0,67) the material will be annealed (under vacuum) in several temperatures up to 800oC. The microstructural characterization will be performed via Vickers microhardness and optical (OM) a…
Duplex stainless steels (DSSs) have a microstructure comprised of approximately equal amounts of fcc austenite (g) and bcc ferrite (±), arranged in alternate lamellae. These steels have good mechanical properties and high corrosion resistance, which allow their use in chemical and oil and gas industries. The so-called lean duplex stainless steels (LDSSs) possess lower contents of nickel a…
In the last decades, advanced high strength steels (AHSS) have been widely used in automotive industries due to their outstanding mechanical properties. These steels are based on Fe-Mn-C system and combine good strength and ductility. During deformation, Fe-Mn-C steels present several complex work hardening mechanisms, which are closely related to their metallurgical parameters. Among suc…
