Duplex stainless steels are widely used in many fields due to their excellent corrosion resistance and mechanical properties. However, it is a challenge achieve duplex microstructure properties through additive manufacturing. In this work, 0.09% N 25Cr-type steel was prepared by manufacturing (AM) heat treatment, its investigated. The results show that, compared with S32750 conventional process, the combination value of film charge transfer AM increased 3.2–5.5 times pitting potential more...
Abstract The effect of 1.5% Cr on the corrosion resistance low‐alloy steel in a simulated mine environment was studied. To clarify wet at initial stage corrosion, salt spray tests were performed to simulate process field, and bare products characterized. results showed that addition reduced surface potential kinetic tendency reaction, making rate test lower than anticipated. An increase content significantly elevates level α‐FeOOH. product film (CPF) had bilayer structure, with α‐FeOOH...
This paper investigates the influence of niobium on thermal stability ultra-fine bainite microstructures and their mechanical properties by means an isothermal transformation at 340 °C, followed tempering in range 200–700 °C for two medium-carbon, carbide-free bainitic steels with without 0.018 wt. % Nb. The results reveal that microstructures, especially film-like retained austenite, is refined, average carbon content austenite also improved as a result addition Nb element. Both this...
Abstract The corrosion behavior of 5.5%Cr–8.5%Cr steels in a CO 2 environment was studied. To clarify the effect Volta potential on uniform and pitting corrosion, weight loss test, electrochemical measurement, scanning electron microscope, energy dispersive spectrometer, confocal laser Kelvin probe force microscope were conducted. results show that there is linear relationship between surface steel substrate self‐corrosion potential. increase Cr content reduces increases potential, reducing...
In this study, the CO2 corrosion behavior of 5% Cr martensite and ferrite-pearlite steels has been investigated by analyzing their products, surface morphologies, cross-sectional elemental distributions. The results electrochemical studies demonstrated that with different microstructures exhibited pre-passivation characteristics, which decreased rates. produced passivating layers consisted Cr-rich compounds, significantly affected steel properties, while correlation between observed Volta...
Recently, the key obstacle of proton exchange membrane fuel cell (PEMFC) development is higher manufacturing cost. In a PEMFC stack, bipolar plate main and multifunctional component, which accounts for 60%-80% total weight 30%-45% stack So forming cost will influence entire costs. Metal plate, can satisfy requirement, be used mass production to reduce Finite element analysis (FEA) stamping springback metal studied by ANSYS/LS-DYNA feasible.
The corrosion behavior of three medium-Cr alloys in CO2 aqueous solution environment was studied by high temperature autoclave accelerated test and electrochemical means (including micro-potential test). In this environment, the rate 5Cr sample 1.5023 mm/a, 7Cr 0.2471 9Cr 0.0540 mm/a. product film consisted two layers. inner amorphous FeCO3 Cr(OH)3, outer layer granular CaCO3. dense rich Cr, which provided effective protection for tested steel corrosive environment. Increasing Cr element...
In this paper, the deformation behavior of S32750 duplex stainless steel during low cycle fatigue was studied by controlling number cycles. The microstructure specimens under different cycles characterized optical microscope (OM), scanning electron (SEM), backscatter diffraction (EBSD) and transmission (TEM). Microhardness two phases measured a digital microhardness instrument. results showed that ferrite increases significantly after first 4000 cycles, while austenite shows higher strain...
