Assessment of thermal embrittlement in duplex stainless steels 2003 and 2205 for nuclear power applications
Duplex stainless steels are desirable for use in power generation systems because of their attractive combination of strength, corrosion resistance and cost. However, thermal embrittlement at intermediate homologous temperatures of 475 C and below, limits upper service temperatures for many applications. New lean grade duplex alloys have improved thermal stability over standard grades and poten...
متن کاملEffect of Thermomechanical Processing on the Microstructure and Mechanical Properties of a Duplex Stainless Steel
Duplex stainless steels (DSSS) have a microstructure composed of ferrite and austenite phases that gives them a very good combination of mechanical and corrosion properties. These steels are desirable for many applications in the chemical and petrochemical industries. In the present study, a type of stainless steel was cast, solution annealed at 1200°C for 60 min and then quenched in water. Ini...
متن کاملInfluence of Initial Microstructure on Hot Deformation Behavior of Duplex Stainless Steels
In this research the effect of initial microstructure on hot deformation behavior in terms of Ferrite-to-Austenite ratios is studied. Two types of stainless steels C1 and C2 were homogenizing heat-treated and deformed under hot compression examinations at temperatures 900ºC and 1100ºC at strain rate of 0.1s-1. The results showed that the flow stress levels of specimens are strongly r...
متن کاملReal Time Imaging of Deuterium in a Duplex Stainless Steel Microstructure by Time-of-Flight SIMS
For more than one century, hydrogen assisted degradation of metallic microstructures has been identified as origin for severe technical component failures but the mechanisms behind have not yet been completely understood so far. Any in-situ observation of hydrogen transport phenomena in microstructures will provide more details for further elucidation of these degradation mechanisms. A novel ex...
متن کاملStudy on Static Recrystallization Process in Duplex Stainless Steel 2205
Steel 2205 is one of the most famous duplex stainless steels. The microstructure of this steel composed of ferrite and austenite in similar amount. Therefore, in order to improve mechanical properties through microstructure, thermo mechanical processes such as controlled hot rolling and forging should be applied. It is not possible to employ the usual heat treatment. It shows the importance of ...
